This VI uses the NI-IMAQ for USB drivers to continously acquire an IMAQ image.

The USB camera is selected from a list generated from the "IMAQ USB enumerate cameras" vi.

Grab rate is controlled using an event structure. This is so that image processing routines can use other event cases.

*Tested with a Logitech QuickCam IM
