I got that error when I set up my byte buffer too small. To fix this issue, I set it to the maximum size that I got from the endpoint description of the reading endpoint (ENDPOINT_DIRECTION_IN, 0x81), instead of 4 bytes (8 in your example) that I had the impression would be enough to contain the answer. Hope that helps some people.

It seems my rfid reader (http://www.sycreader.com/index.php/en/walkthroughmetaldetector/317.html) device is not working with libusb driver. I install Zadig to replace default windows driver (HidUsb (v6.1) with libusb 1.3 driver and exam the device that is not working properly.
usb4java uses native libusb 1.0, I think it can't work.
