Hello Laurent and others linux-uvc developers,

I want to know what is the "struct usb_device *udev" of my webcam.
Have I to search in /sys/devices/pciXXXX:XX/XXXX:XX:XX:XX/usbX/
directory?
I think that you should know a function that helps me in this work :-).

I need it because I want to get some control information of my webcam:
maximum packet sizes, resolutions of still image formats, ...
I think that I should use uvc_probe_video for getting this
information, after I uvc_init_video my webcam.

Thanks
Palmax
