Hello Jean-Francois,
I have a Trust 610 LCD PowerC@m Zoom camera which can operate in webcam mode
also (USB ID=06d6:0031). I tried to use it together with Linux 2.6.28 and with
xawtv-3.95.dfsg.1 and with gqcam 0.9.1. The /dev/video0 appeared, but no usable
picture was visible.
However, I downloaded http://mxhaard.free.fr/spca50x/Download/gspcav1-20071224.tar.gz
and applied the attached patch (which might be incorrect for some aspects).
So I was able to compile the module and both xawtv and gqcam showed the good
picture.
Do you have any idea why the gspcav1 diver is working and the one which is included
in Linux 2.6.28 not?
Here is the output of v4l-info with the patched working gspcav1 driver:

The gspcav1 is not maintained anymore.
It seems that your webcam has not been tested with gspcav2.
First, did you use the v4l library and its wrapper when running xawtv
and gqcam?
Then, have you tried my program svv?
If nothing works, please, send me the kernel traces and the image.dat as
indicated in the gspca_README.txt of my page.
Best regards.

Yes, I found your status at page http://moinejf.free.fr/webcam.html .

I don't really know, I just installed the xawtv package coming with Debian.
> Then, have you tried my program svv?
I could get the Trust 610 LCD PowerC@m Zoom's webcam mode working with
2.6.28 by doing the following steps:
1. download and compile http://people.atrpms.net/~hdegoede/libv4l-0.5.8.tar.gz
2. download and compile http://moinejf.free.fr/svv.c
3. export LD_LIBRARY_PATH=./libv4l-0.5.8/libv4lconvert/
4. run svv
I tested the following settings, all were working correctly:
$ ./svv
raw pixfmt: JPEG 464x480
pixfmt: RGB3 464x480
mmap method
$ ./svv -m r
raw pixfmt: JPEG 464x480
pixfmt: RGB3 464x480
read method
$ ./svv -m u
raw pixfmt: JPEG 464x480
pixfmt: RGB3 464x480
userptr method
What I recognised is that the gspcav1 with xawtv delivered pictures
in resolution of 288x384, while the version in 2.6.28 in 464x480. I
guess this is an improved resolution, but I don't know why the aspect
ratio changed (288/384 = 3/4 = 0.75, 464/480 = 29/30 = 0.9667).
Thanks for your help!

Márton Németh
