When I first was testing the sata boot, I did not have the sata drive connected properly, and I watched the system also try to scan usb. So I thought, that maybe usb boot was also enabled. I powered down and did the sata test successfully.
So this evening I put the partitions on an IDE drive connected via a USB adapter. The drive is rated at .5A, and works fine on my notebook. 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
is those of us with a SATA port have sata boot. Those without will have to at least keep the /boot partition on the SD card to point to the USB drive.
Here is the console capture:

USB1: USB EHCI 1.00

scanning usb for storage devices... 0 Storage Device(s) found
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.
