Hi JF
thanks for your suggestion , I modified sonixj.c compiled and reloaded the driver
but unfortunately I get the same (wrong) picture as before .
I put some mild debug in /etc/modprobe.conf
options gspca_main debug=0x000f
here is the result in dmesg :
----------------------------------------------------

gspca: probe ok
