usb4java's Introduction

usb4java

USB library for Java based on libusb 1.0

See LICENSE.md for licensing information.

This library can be used to access USB devices in Java. It is based on the native libusb 1.0 shared library and reflects this API as complete as possible. usb4java also implements the javax-usb (JSR80) API. So you can choose if you want to access the USB devices via the low-level libusb 1.0 API or via the high level javax-usb API.

The native libraries are included in pre-compiled form for Linux, Windows and Mac OS X in 32 and 64 bit versions. The libraries are automatically extracted and loaded so you don't need to care about them.

For more detailed information please visit the usb4java website.

usb4java's Issues

Failed to load library on ARM (java.lang.UnsatisfiedLinkError)

I'm trying to use usb4java to make an android accessory from a robot controller with an ARM process running a version of Angstrom. I'm currently not able to get the library to load properly.

1.0.0-SNAPSHOT does not properly handle InterfaceDescriptor.extra

The data placed in the InterfaceDescriptor extra() ByteBuffer is not actually the 'extra' data, but is instead the beginning of the Descriptor. I believe the following will fix it, but I've not yet been able to compile it properly so I'm not 100% sure:

ARM Linux (Raspberry Pi) : UnsatisfiedLinkError / No such file or directory

Hi.

I was trying to get this working on a Raspberry Pi, which is on of the most popular Linux ARM devices.

Even when trying to execute a simple example (this one), I get an error:

Somehow it looks like the native library is not being copied to the temporary file.
I also tried to run the application as root user, but the same happens.

Any hints?

High Level javax.usb API not working

I tried your example using the low level API and was able to get a listing of all USB devices on my machine. I tried the high level API and got nothing, the dump gave me

ffff:ffff

and nothing else. Why would the low level API work and not the high level? I also tried directly creating an instance of your de.ailis.usb4java.Services class and that gave the same output as aobe.

I am using usb4java version 0.5.0 and jsr80 1.0.2. I have a javax.usb.properties which has

javax.usb.services = de.ailis.usb4java.Services

I am running Linux 12.04. Looking for libusb, I find

/lib/i386-linux-gnu/libusb-0.1.so.4
/lib/i386-linux-gnu/libusb-0.1.so.4.4.4
/lib/x86_64-linux-gnu/libusb-0.1.so.4
/lib/x86_64-linux-gnu/libusb-0.1.so.4.4.4
/lib/x86_64-linux-gnu/libusb-1.0.so.0
/lib/x86_64-linux-gnu/libusb-1.0.so.0.1.0

Given the low level API is working, I would claim it isn't confused between the 32 bit and 64 bit versions.

Thoughts?

Perhaps for now I should use the low level API, though I would rather not.

pipe.close()

Hello Klaus,

I'm picking up your work (v0.3.4) for a project that is about to come up, and while working with it I've found a possible bug and it's solution. It''s around opening and closing a pipe (JSR80 API):

The code where error happens:

    try
    {
        pipe.getUsbEndpoint().getUsbInterface().claim();
        pipe.open();

        int bytesWriten = pipe.syncSubmit(message);
        assertEquals(bytesWriten, message.length);
    }
    catch (UsbException ex)
    {
        Logger.getLogger(UsbTests.class.getName()).log(Level.SEVERE, ex.getMessage(), ex);
        assertTrue(ex.getMessage(), false);
    }
    finally
    {
        pipe.close();
        pipe.getUsbEndpoint().getUsbInterface().release();
    }

An exception occurs @ pipe.close(); (exception message "Pipe is still busy", on LibUsbPipe line 168)

I've looked over at AbstractIrpQueue.isBusy() method, and perhaps the bug is there:

Existing code:

public final boolean isBusy()
{
    synchronized (this.irps)
    {
        return this.irps.isEmpty() || this.processor != null;
    }
}

It is testing if irps queue is empty, while it should be testing if is not empty. Changing the line to the following, solved my problem:

public final boolean isBusy()
{
    synchronized (this.irps)
    {
        return !this.irps.isEmpty() || this.processor != null;
    }
}

Do you agree with this solution?

Thank you very much, keep the good work!

not an issue but request for some examples

I am able to verify the setup for usb4java.jar in my java project, could some one point me to the samples on how to read and write a file / data to a usb hard drive ?

I have connected the USB hard drive to the laptop however when I print the value of device.getProductString() I just read vitual Root hub. This is on windows 7, please let me know what might be the issue.

Also is there a mailing list for this library to get help ?

Thank you

High Level javax.usb API not working on Windows 7

I am getting the same problem on Windows 7 as was resolved a month ago on Linux. It is returning two devices I have attached on the low level code but the high level only sees the hub. What is the fix on Windows 7?

libusb 1.0

Are there any plans to support the libusb 1.0 API?

usb4java 1.2.0 crashes on OS X 10.10.2 Yosemite

The following code fragment from one of the examples crashes the JVM:

DeviceList list = new DeviceList();
int result = LibUsb.getDeviceList(null, list);

On OSX, device updating fails after some time

In regards to my post on the board: https://groups.google.com/forum/#!topic/usb4java/qrcz4H9n_jY

More information is provided there, but basically on OSX after running the software for a while (with some device failures and reinits happening every hour). After a while the device list seems to stop getting updated, and i cannot open an interface to the device. Oddly enough, when walking the device tree at this point, it is never updated. Unplugging the old device, plugging in a new one, etc. still returns the same list of devices. I'm still getting callbacks from control requests, but obviously with no device it does nothing. Trying to send data, I get a failure that it cant find the interface. This sometimes results in a segfault (attached).

Moving the software over to linux, everything works fine. I may try compiling my own OSX native driver and see if that helps.

Attach/detach usb event

Hi, Klaus!

I want to catch attach/detach event for usb devices from java on Windows and Linux but can't find any working solutions...

I try to use "javax.usb" with yours and http://javax-usb.cvs.sourceforge.net/javax-usb/javax-usb-libusb/ implementations on Win7 x86 but events not thrown:

Services services = Services.getInstance();
services.addUsbServicesListener(new UsbServicesListener() {
    @Override
    void usbDeviceAttached(UsbServicesEvent event) {
        // Never caused
    }

    @Override
    void usbDeviceDetached(UsbServicesEvent event) {
        // Never caused
    }
});
while(true) { ... }

In last version of usb4java i found "hotplug_callback", will it solve my problem? Is there a binaries of newest "libusb4java" with "hotplug_callback" implementation? (can't find it on site).

Is there a better solution for this problem on java?

Thanks!

usb4java 1.2.0 on OS X 10.6

I've been having issues with usb4java 1.2.0 on OS X 10.6.
When I run the simple device listing example it returns no error and no list of devices.

After I recompiled libusb4java with libusb installed with brew install libusb, now it works.

Any on ideas on where I should look for differences between what is bundled in libusb4java-1.2.0-osx-x86_64.jar and my locally compiled version? Perhaps 1.2.0 was compiled with an older libusb? or Perhaps it was compiled on 10.7 or higher, so the libusb is not compatible with 10.6?

javax.usb.UsbPlatformException: USB error 12

SIGSEGV on Mac 10.7.4 & JDK 1.7.0_21

I'm unable to get the Dump example to work. I've verified that the correct native lib (OSX 64) is being referenced.

javax.usb.UsbPlatformException: USB error 12

when I am running I am getting error
javax.usb.UsbPlatformException: USB error 12: Unable to claim interface: Operation not supported or unimplemented on this platform
I have successfully run all high level examples.But when I run UsbInterface.claim() function I am getting this error.Usb devices that I have used is Webcam (made in china) ,HP Scanner,ZTE Modem.I have tested all three drivers WinUSB, libusb-win32 and libusbK but all give same error.

Can't claim device on Mac

After a few days with usb4java, I've successfully:

Disable System Integrity protection on OSX 10.11.3 "El Capitan" via stackexchange/a/208481 so that non-signed kernel extensions can be used. (yes, this is mandatory for non-signed kernel extensions now 🔥 ).
Implemented an OS X kext kernel extension to prevent kernel driver from claiming device by vendorId and productId per libusb/wiki/FAQ

... but the device's UsbConfiguration won't come back as "active". What I mean is... usbDevice.getActiveUsbConfiguration() returns null.

So my next step was to grab the first UsbConfiguration available. I did this by:

for (Object o : usbDevice.getUsbConfigurations()) {
   if (o != null) return (UsbConfiguration)o;
}

Which allows me to successfully do things like usbInterface.getUsbInterfaceDescriptor(), usbEndpoint.getUsbEndpointDescriptor(). These list/return the device interfaces and endpoints correctly. (The device is a USB scale, if that matters).

However, when I try to claim the device, I get the following exception:

Configuration is not active

This leads me down some paths of using the Low-Level API to set the active alternate configuration (bAlternateSetting?), but I'm starting to get lost. Is there a way, using the High-Level API to set a particular UsbConfiguration as active for a specified UsbDevice? Edit: Tried and it didn't change anything. Crawling the internet suggests explicitly setting the active configuration may not be uncommon but I'm having a hard time understanding how to do that with either API. Any help appreciated. 👍

On a side note, some Google searches let me to improper behavior of the USB device itself, but this particular device is from a major manufacturer and working fine on Ubuntu and Windows.

AbstractDevice doesn't allow for multiple claimed interfaces on the same device

I have a USB device that requires multiple interfaces to be claimed at the same time. AbstractDevice currently only allows a single interface to be claimed at any one time. I added a fix in my pull request to use a set of claimed interface numbers.

Can't find dependent libraries

I am using a Win 7 Pro 64-bit machine. My development is on an Eclipse clone called MyEclipse. It is based on Eclipse 3.7.2.

I have downloaded usb4java v0.5.0. I also have downloaded the jsr80 file jsr80-1.0.1.jar. Now I am trying to run the first example on the quickstart page that uses the low-level API to list the devices. When I try to run the code I get the following error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: C:\Users\JavaGeekGP\AppData\Local\Temp\usb4java1464949704274749313.tmp\libusb4java.dll: Can't find dependent libraries

What did I do wrong?

Linux - kernel driver won't release IN endpoint

I'm attempting to use usb4java for the HID interface on the Funcube Dongle Pro Plus, which has a HID interface (#2) with IN/OUT interrupt type endpoints.

I can claim HID interface #2, get the IN (0x82) endpoint and OUT (0x2) endpoint and create a pipe against both.

When I send a data IRP over the OUT pipe and then try to read the response IRP back over the IN pipe, I get all zero values in my IN response buffer. Then, the next time I run the code, it hangs for a second and then I get the following exception:

de.ailis.usb4java.exceptions.Usb4JavaException: USB error 110: Unable to read from interrupt endpoint: could not detach kernel driver from interface 2: No data available
at de.ailis.usb4java.support.IrpQueue.interruptRead(IrpQueue.java:213)
at de.ailis.usb4java.support.IrpQueue.processIrp(IrpQueue.java:98)
at de.ailis.usb4java.support.AbstractIrpQueue.process(AbstractIrpQueue.java:94)
at de.ailis.usb4java.support.AbstractIrpQueue$1.run(AbstractIrpQueue.java:67)
at java.lang.Thread.run(Thread.java:722)

This is a consistent cycle ... it works the first time, then throws an exception the next time.

It appears that the linux kernel driver is retaining control over the IN endpoint and intercepting my data IRP response.

Am I doing something incorrect?

Thanks in advance for your assistance,
Denny

java.lang.UnsatisfiedLinkError on BeagleBone running Ubuntu

Hello,

We are using usb4java-1.0.0.jar to access USB devices on our various Linux distributions. The library works fine on our 32-bit Linux Mint distro and BeagleBone Angstrom distribution.

However, we are trying to run the BeagleBone with Ubuntu (13.0.4). When we run our code, we get the following error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: /tmp/usb4java7866977171456936988.tmp/libusb4java.so: /tmp/usb4java7866977171456936988.tmp/libusb4java.so: cannot open shared object file: No such file or directory
at java.lang.ClassLoader$NativeLibrary.load(Native Method)
at java.lang.ClassLoader.loadLibrary1(ClassLoader.java:1965)
. . . .

Would you have any idea why this might be happening?

Do you have any suggestions on how to fix it? Or any potential work-arounds?

Thanks for any assistance you can give.

Hello i've baught Device ODroid X2 from this site :

http://www.hardkernel.com/renewal_2011/products/prdt_info.php?g_code=G135235611947

i was trying to use it's abilities like USB interface & UART , etc ... i am new at programming i learned some C# and taught my self some JAVA i am still new on them , i've downloaded a USB api called usb4java from this site :

http://kayahr.github.io/usb4java/

i've used most of tips & hints there , it worked on win xp,7 and on ubuntu with processor intel , but it can't get any output on my ARM processor device , so could any one help me to communicate with USB api via java with ARM processor ?

Are files missing that are required to build the libusb4java.so "C" code?

We are wanting to build the libusb4java.so as explained on the page https://github.com/usb4java/usb4java/tree/master/src/main/c.

The instructions say to run these two commands:

$ ./configure
$ make

However, in looking at the contents of that directory, there is no "configure" or "Makefile" files present. Am I missing something, or do those files need to be added to Github?

Ångström Beagleboneblack Java Issue

Hello,
I'm having some troubles in work with Java-linux-arm library, I created a project in Netbeans with usb4java version 1.2.0 using libusb4java-1.2.0-linux-arm.jar and windows-x86 64.jar to a comunication between Ångström Linux and Windows 7 64 but when I go to run the jar file in linux this appears:
The command used to run the Jar: java -Djava.io.tmpdir=/home/root/Desktop/temp -jar Java4USB.jar
That was to be certain that the folder have the rights to Write and Read.

If anyone can help I will be grateful,
Thanks in advice

low level libusb interface requires javax.usb in the 1.0SNAPSHOT code

in 0.5 I was able to (I think) use the libusb portion without needing to have javax.usb installed. With the current trunk, I must have javax.usb installed even though I exclusively use the low-level API.
I believe this is because of the following line in libusb/InterfaceDescriptor.java:

public final class InterfaceDescriptor implements UsbInterfaceDescriptor

It isn't a big deal, but it would be nice if this wasn't needed.

By the way, I really appreciate the existence of usb4java. Thank you for developing it.

Timeout and abort irp

Hi folks,
I'm a bit annoyed that I just can't abort irp when timeout has a big value (or you must may for all timeout to be exceeded, without speaking of the 0 case).

I think IRP model misses a irp.cancel() method.

What do you think ?
Though it might not be the right place to talk about this, I probably shall complain onto javax.usb project page ...
Cheers,
Topaz.

Bulk write to Vx810 Pinpad

I have a problem with this exception in Windows ( in linux wors fine )
USB error 5: Transfer error on bulk endpoint: Entity not found
This exception is produced by async Submint of UsbIrp in output endpoint. The data is only a 0x15 ( one byte)
I cant get more infromation it to try to resolv.
When I use a for Exmaple Ingenico IPP320 pinpad( only change the input endpoint number ) it works in linux and windows.
In linux for booth device I use de Winusb driver instaled using zadig (WinUSB (v6.1.7600.16385))
Could you help me?
Thanks

Java WebStart support

Lib is not working on Java WebStart.
No erros happen, but no devices return in root.getAttachedUsbDevices();.

If same program run on standalone mode (using Netbeans to launch for example)
every device is listed.

If you do a invalid configuration for JNLP, like don't import natives or usb4java lib, erros occurs.

Connection crash on Windows 7

I'm using v1.0.0 and connection to devices in Windows7 is messy, this means, I can't connect most of the times. I need to force connection several times to be able to use the device. Do you think this is a bug or something related to the device and driver ?
In windows 8 all works well.

Thanks a lot

Possible race condition

I got a NPE at one of these rows (don't remember which, but it's insignificant) in AbstractIrpQueue.add():

        this.processor.setDaemon(true);
        this.processor.start();

I guess it happened because processor is set to null at two locations in process() allowing it to be set to null again after it is recreated in add(). processor should probably also be declared volatile since it's accessed from multiple threads.

Devicelist returned from LibUsb.getDeviceList not actualized

In my setup, Linux Centos 6, Java version 1.8.0_102-b14 I noticed the following:

When an USB device is added or removed from the bus, a followed LibUsb.GetDeviceList is not updated with this event. The same number of devices is returned.

I tested it with the native libusb-1.0.20, and there seems to work correctly.

After doing a new LibUsb.init, the list is indeed actual again, but this is not what you expect, since the native function does it well.

EXCEPTION_ACCESS_VIOLATION in LibUsb.interruptTransfer (Windows 7 x64; Oracle JDK 7u51)

Hi,

first of all thanks for a great javax.usb implementation. It works like a charm on my ubuntu installation. I just tried to run the same code under Win7 x64 with the Oracle HotSpot 7u51 JDK.

I am able to pull usage page+id information from a HID device. But when I try to do a syncSubmit on the devices interface pipe the JVM crashes with an access violation.

Let me know if I can help in any way to solve this (or maybe workaround).

UnsatisfiedLinkError

Hi,
I think I spotted a bug in the software. When the method usb_init() in windows is created a temporary folder which will wold libusb4j.dll and libusb0.dll. libusb4j.dll for my understanding is dependent on libusb0.dll so when you guys try to load libusb4k.dll without having loaded libusb0.dll. The exception UnsatisfiedLinkError will occur under windows OS x64. To fix this I have changed the code in Loader.java under the function load to the following:

public static void load() throws LoaderException
{
if (loaded) return;
final String[] path = extract();
if(path[0]!=null){
System.load(path[0]);
}
System.load(path[1]);
loaded = true;
}

And the function extract to the following:

private static String[] extract()
{
final String platform, lib, extraLib;

    platform = getPlatform();
    lib = getLibName();
    extraLib = getExtraLibName();
    String dependentName = null;
    if (extraLib != null) {
         dependentName = extractLibrary(platform, extraLib);
    }
    String libraryName = extractLibrary(platform, lib);

    return new String[]{dependentName, libraryName};
}

The following issue on stackoverflow as helped me to solve the problem.

http://stackoverflow.com/questions/6092200/how-to-fix-an-unsatisfiedlinkerror-cant-find-dependent-libraries-in-a-jni-pro

Even though they say it is alright to do it as you guys did :S but the fact is that the Exception was being thrown any way.

Hope this will be usefull, thank you for the development of this software by the way.

Unable to initialize libusb: 99 Other error

Dear Friends,
I am trying usb4java for USB printer. When I run my java Program i got the following error.

/root$ java -jar 1USBPrint.jar
libudev: udev_monitor_new_from_netlink_fd: error getting socket: Invalid argument
Exception in thread "main" org.usb4java.LibUsbException: USB error 99: Unable to initialize libusb: Other error

Please check and suggest for the solution

Bulk transfer timeout on in-driection pipe

Reading the example at http://javax-usb.cvs.sourceforge.net/viewvc/javax-usb/javax-usb-example/src/MouseDriver.java?revision=1.1&view=markup, I was under the impression that a sync submit on such a pipe should block indefinitely:

294     try {
295     /* This is synchronous, meaning our Thread will
296     * block until the data buffer has been filled by the device.
297     * For non-blocking submission, the asynchronous method should be used.
298     * Note that interrupt-in (and bulk-in) pipe submissions may
299     * block indefinitely! Control-type and isochronous-type submissions
300     * will complete (or fail) in a finite amount of time; the USB spec
301     * arbitrarily sets this time limit at 5 seconds, but YMMV with
302     * various implementations. Interrupt-out (and bulk-out) shouldn't
303     * block indefinitely.
304     */
305     length = usbPipe.syncSubmit(buffer);

This is only the case with de.ailis.usb4java.timeout set to zero. Should this global value affect these transfers, or is this a bug?

Bulk transfer and splitting

Hi,
I'm a bit struggled with the automatic split made during bulk transfers over endpoints. I'm talking about splitting loops with the maximal endpoint size made in IrqQueue.java.
For example, if playing with a massstorage onto a linux host, you can send straight the whole data to send over bulk endpoint to the libusb. On this side, I think an IRP could be set as "non splittable" to avoid such splits.

For reference:

private int read(final byte[] data, final int offset, final int len)
    throws UsbException
{
    final UsbEndpointDescriptor descriptor = getEndpointDescriptor();
    final byte type = this.pipe.getUsbEndpoint().getType();
    final DeviceHandle handle = getDevice().open();
    int read = 0;
    while (read < len)
    {
        final int size =
            Math.min(len - read, descriptor.wMaxPacketSize() & 0xffff);
        final ByteBuffer buffer = ByteBuffer.allocateDirect(size);
        final int result = transfer(handle, descriptor, type, buffer);
        buffer.rewind();
        buffer.get(data, offset + read, result);
        read += result;

        // Short packet detected, aborting
        if (result < size) break;
    }
    return read;
}

I'm replacing the call to pipe.asyncSubmit(data) with:

ByteBuffer bb = ByteBuffer.allocateDirect(data.length);
bb.put(data);
IntBuffer ib = IntBuffer.allocate(1);
ib.put(data.length);
LibUsb.bulkTransfer(deviceHandle, pipeOut.getUsbEndpoint().getUsbEndpointDescriptor().bEndpointAddress(), bb, ib, timeoutDelay);

Which works like a charm, but annoy me in term of design.

Thanks for any comment on this.

Device connected to USB3 port not contained in device list

The low level function LibUsb.getDeviceList works well for normal USB ports, but if the device is connected to a high speed port of my laptop, it is not contained in the device list.

I'm using WinUSB driver on Win7. The device shows up in Windows device manager list.

Not able to receive any data on an In Endpoint

I am on Ubuntu 13.04, 64 bit and trying to connect to an Android Device.

I am able to write to the device but not able receive any input callbacks. I am using usbmon to trace the packets.

After opening the input endpoint, do I need to do anything else before calling addUsbPipeListener?

Thanks!

Native library not found exception for usb4java usage in android device

I want to develop usb application with usb4java for Android device. I'm using Android Studio as an IDE and Ubuntu 14.04 as an operating system. I have added usb4java-1.2.0 file to my project. I can use Libusb function in my application. Firstly I wrote LibUsb.init() function in my MainActivity but there is an error about native library. I'm getting classloader exception.

Caused by: org.usb4java.LoaderException: Native library not found in classpath: /org/usb4java/linux-armv7l/libusb4java.so

I have analyzed Unsupported Platform tag in http://usb4java.org/nativelibs.html website. But I couldn't solve my problem with this way. After that I read https://github.com/usb4java/libusb4java and again I couldn't solve my problem with your way. Can you help me please.

code is on Windows XP sp3 with Java 7. and libusb-1.0.dll, libusb4java.dll. The code runs very intermittently on Windows, for example after GoldenCheetah has accessed the USB Stick (but only works very rarely in this case).

high-Level API - javax.usb , support the Mac OS?

usb4java support linux, os x(mac os), window
but,,,javax.usb support linux only. (abandone window implementation, not support OS X)
[http://javax-usb.sourceforge.net/]

High Level javax.usb AP, support the MacOS ??
I need API about finding usb devices in Mac OS.
