[Spca50x-devs] 0ac8:307b Z-Star Microelectronics Corp. USB 1.1 WebCam




Ciao!
I'm davide from italy (sorry for the grammar),
and i'm trying to activate the webcam Z-Star with the "Jef Moine" driver: gspcav2-2.0.3 <http://moinejf.free.fr/gspcav2-2.0.3.tar.gz>
on the website it seems to work..


The drivers compilation and installation goes well,
the modules loading too,
but the webcam seems doesn't work :-(


I did as advised Jef:


1) - do
                       echo 0x3f > /sys/module/gspca_main/parameters/debug

2) then start the application, and send me the last kernel
                 messages:
