Identifying a USB camera

[Richard Miller]

How can I access a camera through Rev? I plugged in a Canon Powershot  
camera (USB). It shows up in My Computer with its name, but no volume  
number. THE VOLUMES function in Rev doesn't see it. I suppose I could  
use the Registry, but I'm hoping for some other approach. I need to  
be able to identify any camera plugged in via USB without knowing the  
model in advance.

Thanks.
