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:

Code:
[email protected]:~# 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,
