I use Debian, xfce and kernel 220.127.116.11
I have this webcam
Bus 002 Device 003: ID 064e:c108 Suyin Corp.
If i use cheese, sometimes i have the next error
cheese: Fatal IO error 11 (resource temporarily unavailable) on X server :0.0
Sometimes it opens correctly but if i move the mouse or press a key it closes.
Other times i get this
cheese: ../../src/xcb_io.c:242: process_responses: Assertion `(((long) (dpy->last_request_read) - (long) (dpy->request)) <= 0)' failed
cheese: Fatal IO error 22 (invalid argument) on X server :0.0.
With camorama, it says that it cant find /dev/video0
Now, if i use luvcview, it works perfectly ok.
Now, at least, i know that it's not an error from xfce.
