The log show that usbvision module is loaded but fails to set altsetting to 1.

Yes, I've just noticed this. Perhaps, you could try using vlc and/or mplayer (instead of cheese) and also try to use explicit device, i.e. /dev/video1 and/or /dev/video2. But if the driver fails to set alternate setting, then it will never work, right? Hope this helps, Ezequiel. ^ permalink raw reply [flat|nested] 10+ messages in thread
