Please try a 8.1-STABLE or 8.2-PRERELEASE snapshot (you can boot the
livefs CD or USB memstick image to test) and see if things are different
(improved) there.

8.x uses a newer/different USB stack than 7.x.

Finally, when you say "the camera", are you talking about a webcam, a
digital camera with an SD or CF card, or what?  "The camera" doesn't
really describe the product.  The reason I ask: umass is for storage
devices; a webcam shouldn't be appearing as a storage device, while a
SD/CF/etc. card in a digital camera should.
