Hi, Tom.

I'll be along this evening with my vastly improved Parallella: Got a
theory about why the USB is unreliable if anyone knows about USB VBUS
and OTG. My fix is to cut the +5V (red) wire in the upstream USB cable
to stop my not so cheap but non-compliant Belking USB hub back-feeding
power to the Parallella through its USB OTG connector. Apparently this
is a well known problem on the RPi, but I didn't know about it before!

Bye,

  Tony.
