    Hey,
    I'm working on the new Cyclone V SoCFPGA, using the SoCrates-Development-Board, and having some trouble with my Webcam Logitech C920. I work with the kernel version 3.9 (also tried it with 3.8 - sources via http://rocketboards.org/gitweb/?p=linux-socfpga.git), and get following messages when trying to bind the cam to the system:

    Code:
    root@socrates:~# dmesg | grep usb
    usbcore: registered new interface driver usbfs
    usbcore: registered new interface driver hub
    usbcore: registered new device driver usb
    usbcore: registered new interface driver usb-storage

    usbcore: registered new interface driver uvcvideo
    
    Code:
    root@socrates:~# dmesg | grep uvc
    uvcvideo: Found UVC 1.00 device HD Pro Webcam C920 (046d:082d)
    uvcvideo: Failed to query (129) UVC probe control : -110 (exp. 26).
    uvcvideo: Failed to initialize the device (-5).
    usbcore: registered new interface driver uvcvideo
    
    Linux recognizes the camera, but can't initialize the device. Already read about the solution that unloading and reloading the uvcvideo-module helps, but I can't confirm that. Connecting the camera to a normal computer using Ubuntu 12.04 worked...:/


    Thanks for reading,
