How many times do I have to say that I tested exactly what you said you
tested (granted, we're probably using different size and brands of usb
thumb drive), and couldn't reproduce the problems at all?  I plugged the
memory stick both into a powered hub, and directly into the beaglebone.
I used the exact tar and rsync commands you did, using both nfs and
ufs-on-sdcard as the source drive.  No errors, the copies always
completed.

I think it's looking increasingly like you have bad hardware.
