I plugged it into my Cubietruck and as you will see below, the partitions were found.  The USB adapter was plugged into the top USB port, and a USB hub that has the keyboard and mouse were plugged into the lower USB port.  I have a USB IDE enclosure that provides 1A (one of those with 2 USB male plugs, I can put the second into a USB powersupply) if you think the failure was power related.  I really don't so won't try that test unless asked. Bottom line

Note how u-boot says that it is not seeing any usb storage devices...

My first hunch is that the drive is simply not getting enough power,
try with a usb "stick" type device, that should work.
