You're right: I can get the webcam working with luvcview with or without sending the GET_DEF request, so the driver works around it, the only visible difference is the error msg. It also seems to work with 'motion', but no luck with other programs, like camorama, cheese, camstream or skype. skype doesn't even print any error msg, it crashes and that's it. It keeps crashing until I unload uvcvideo, very annoying. > You could also try not to load the usbaudio driver at all.

Thank you for helping. Bye Carmelo _______________________________________________ Linux-uvc-devel mailing list [email protected] https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
