wifi and webcam C920 connected using a USB host connected to beaglebone

I tested with two chipsets:
chipset 1

After open a MJPEG stream near immediately I got:

So I unplugged the device and then plug another, after some time I got:

Network is down
urtwn0: ieee80211_crypto_encap returns NULL.
% urtwn0: ieee80211_crypto_encap returns NULL.
urtwn0: ieee80211_crypto_encap returns NULL.

So, I remove the camera from HUB, plug it on my notebook. the urtwn stay 
in HUB+Beaglebone. Now, I transmit from my notebook to beaglebone and 
back to notebook. Throughput of

                            rx         |       tx

   time                  5,45 minutes

And no problems. I think that the bug occurs when the webcam and wifi 
dongle are in the same USB HUB. Maybe a electric problem? I'm using a 
external power source to USB HUB.
