Hi,
sorry for reheating my question, but I'm still in search of the
component to blame, that the cam is not working. I understand that the
Linux distro I'm using is in alpha state so problems have to be expected.
It's a Ubuntu Feisty Fawn on a amd64 dual core and uname -a tells me:
Linux fnk64-desktop 2.6.20-8-generic #2 SMP Tue Feb 13 01:14:41 UTC 2007
x86_64 GNU/Linux
Maybe someone can give me a hint on where to tweak the logging to get
more information.
I'm not much of a c-programmer and far off understanding the
architecture of the uvcvideo module, but I should be able to add another
uvc_trace here or there.
Kölle Alaaf,
