USB hubs on beaglebone black?

[Brian J. McGovern]

All,
  I'm having an issue with my BBBs and I'm curious if this is a known
issue. Googling on the keywords I can think of hasn't turned up much
useful. When using webcamd, I can get a camera working fine. However,
when I put a powered USB 2.0 hub between the BBB and the camera, I not
only get no picture, but things like the vendor and device ID change...
I'm assuming there is some corruption going on here, but I only have a
small handful of identical USB hubs to play with, so I'm trying to
determine whether going shopping is "worth it", or whether there is a
problem with the USB stack.
