I am having the same issue. Did you ever find a solution?
Care to expand on what issue your having with what specific device you
currently have?
Regards,
Sorry, I had typed up a longer post, but I think it did not get saved. I
have a USB endoscope camera I am trying to use with a beagleboard.
Admittedly it is an inexpensive unit.
It seems to just hang on the beaglebone black, but works on another ARM
linux board I have tried. I will attach some details from a test on both
boards with the same USB camera
