Good luck.
I downloaded and installed fswebcam and installed Junichi's latest linux-uvc-source package (0.1.0-4). When I rmmod/modprobe uvcvideo, dmesg doesn't say much: usbcore: deregistering driver uvcvideo uvcvideo: Found UVC 1.00 device <unnamed> (046d:08c1) usbcore: registered new driver uvcvideo USB Video Class driver (v0.1.0-b) When I run fswebcam I get: # fswebcam -v -d /dev/video0 --- Opening /dev/video0...

Timed out waiting for frame! No frames captured. Seems like a similar problem as with uvccapture (only fswebcam has a timeout and uvccapture waits forever). Any other suggestions?
