As per Jan Axelson (Author of "USB Complete" and other books), xusb may have a problem when dealing with the extended properties OS feature descriptor. Quote: "I tried libusbx with Microchip's WinUSB example and got the extended compatibility OS feature descriptor OK. The extended properties OS feature descriptor failed because it must be directed to the WinUSB interface (LIBUSB_RECIPIENT_INTERFACE), not the device (LIBUSB_RECIPIENT_DEVICE). The first byte of the Setup packet should be C1h, not C0h. (I didn't try to fix it, just observed what the application sent.) The extended compatibility OS feature descriptor can be directed to the device." -- Xiaofan ------------------------------------------------------------------------------ Everyone hates slow websites.
