gritzman / libusb Goto Github PK

I have to use newest libusb. Although Gritzman's libusb can work, I want know which file been modified, so that I can do it in newest libusb.
I have checked the source code, but because I don't know which version of libusb been modified by Grizman, so I can't modify the source code.

hi, i have a error (return -1) on in libusb_init() for android Oreo non rooted

supports_flag_bulk_continuation = kernel_version_ge(2,6,32);
if (supports_flag_bulk_continuation == -1) {
usbi_err(ctx, "error checking for bulk continuation support");
return LIBUSB_ERROR_OTHER;
}

an idea please?

Please add brief usage on android to the readme, not clear without digging sources:

1. you MUST open device by UsbManager
2. open by libusb
3. close by libusb
4. close by UsbManager

Exactly that order will work.

I see your instructions in the README:

1. you need to open device by UsbManager
2. open by libusb
3. close by libusb
4. close by UsbManager

The substeps for step number 2 are, as I understand them:

1. libusb_init
2. libusb_open_device_with_vid_pid

...but I encounter a problem when attempting to open the device with libusb: libusb_init returns -99. I suppose that this is because my app lacks permissions to access /dev/bus/usb, but is there anything I can do about that?
