So, it should have these bridge and sensor inside.

Do you have some init sequence for the sensor in your .inf file?

At least the driver talks with your cam ;-)

Should be still ok, I think.

Try usbsnoop, this is the preferred snoop tool.

Looks like your cam is similar to the one already in gspca.

Load the gspca module with debug=5 and you get lots of debug information
in kern.log. (sudo modprobe -r gspca; sudo modprobe gspca debug=5 and
plug your cam)

When you run gspca with debug=5 you should see all the i2c messages in
the log. Compare it with the snoop from windows?

I don't know :-(
