Hi,

I just done a quick test under 2.6.24 with my Intel Easy Pc Camera/CS110  (spca508)

While pluging the webcam :

while using luvcview :
( version 0.2.1 )
Video driver: x11
A window manager is available
video /dev/video0

It stay black (no out log in dmesg) and I need to kill -9 luvcview
having after in dmesg :
[  962.037133] gspca: urb out of sequence
[  962.037143] gspca: unknown urb
[  962.038127] gspca: urb out of sequence
[  962.038138] gspca: unknown urb
[  962.039123] gspca: urb out of sequence
[  962.039132] gspca: unknown urb
[  962.040126] gspca: urb out of sequence
[  962.040139] gspca: unknown urb


Same problem with vlc

On Monday I'll look deeper on the problem and also try to get a microdia webcam ("0c45:612f" made of SN9C110 + ICM105) working.


Happy Easter all

Aurelien
