Among these, the UVC and CDC works. If your USB device not recognized in Windows 10 and labelled as Unknown USB Device (Device Descriptor Request Failed), here is how to fix it. It took me a few days messing with the USB composite devices on my UP Board, which also has USB OTG like the pi. The device descriptor describes general information about the device. You cannot use IADs recursively to bind functions of functions. Show content of filename HWMonitor. The descriptor gives the OS two important pieces of information about this interface. I am trying to build an USB composite device (UVC + UAC + CDC). The fix for the situation is really just a matter of reconnecting the device.
