Hi,

I am writing a driver for the ov9655 sensor from Omnivision.
To do so I am using the ov772x.c file as an example.
But I don't understant, because it seems that I never enter the 
video_probe function...
Do you have any idea what could I do wrong? Is it coming from a wrong 
i2c config?

Regards,
Sedji
