Hi Laurent, thanks heaps for the help,

but now the device was complaining that it couldn't initialized  (seemed
like it couldn't find the suitable pic mode):
Do I need to put the 'right' quirks again to let the camera initialized
correctly ?

Thanks again for your help,

Followings are the excerpts:
