That's probably not good enough... Here is how you do it:

a) attach *complete* contents of /proc/bus/usb/devices with your capture
device connected

b) post it on the linux-usb-users list

c) see if anyone recognizes the structure of interfaces.

The problem with the vendor/product numbers is that they have nothing to
do with the actual hardware in your device. Each OEM is even *required*
to plug his own numbers in, even if they all use the same chip! The
Vendor ID 0x7d0 has not even been assigned to anyone until recently,
it's a new one - and the product ID 0x04 is another indication of a very
young product.

Therefore, you need to find out what chip is inside. As I said, you can
post the *complete* contents of /proc/bus/usb/devices on the list and
hope that one of camera driver developers notices similarities. If
nobody responds on the list then probably this chipset is not known, and
not supported either.

Another way is to contact the manufacturer of the device and ask them.

Yet another way is to open the device and look inside. But it requires
familiarity with electronics, since probably you'd need to put the thing
completely apart to read the labels. Also, for convenience, most chip
manufacturers put extremely obscure labels on their chips, so that you
can not determine what chip it is unless you already know it.

I would recommend posting the descriptors, and calling the manufacturer.
Unfortunately, there is no standard on video devices, and so each camera
and capture box do their own thing... and they need special drivers.

Thanks,
Dmitri
