[Spca50x-devs] Problems with LDLC 0x0ac8:0x307b




Hi all,

I am using Ubuntu 8.04 with kernel 2.6.24-17-generic SMP with gspca driver 01.00.20. I have a "Bright 480" camera which is equivalent to a camera recently added to GSPCA:

Release 01.00.19 rc2   
        Add LDLC 0x0ac8:0x307b Thanks Pierre Quelen/Didier Leclerc for the webcam.

dmesg shows the driver is loaded correctly (I am using the options: options gspca force_rgb=1 autoexpo=0 debug=4 GGreen=255 GBlue=255 GRed=255 OffGreen=1 OffBlue=1 OffRed=1 gamma=2 in /etc/modprobe.d/options):
[ 4520.775103] /build/buildd/linux-ubuntu-modules-2.6.24-2.6.24/debian/build/build-generic/media/gspcav1/gspca_core.c: USB GSPCA camera found.(ZC3XX)

However, I couldn't make it work under Ubuntu yet. It works ok under Windows XP. When I try to use gqcam, it shows the controls but nothing on the screen; and if I try to change preferences, stop capturing or even just leaving the program, it freezes. If I use camorama , it simply freezes at start. And when I use camstream, it freezes when I try to change the resolution setting (and no image appears at all).

camstream reports this, before freezing:
(...)

caminfo (from camstream) reports this string: LDLC OV7620+VC302.

camorama reports this:

On dmesg, after trying the camera with there programs, there are lots of warnings:

Can you tell me what could be going wrong? This is a cheap webcam I bought recently, hope I can make it work under Ubuntu since I don't use windows at all.
Thanks and congratulations for the nice job,
