Hi
I got the device, tried it out with a vfat formatted 120G SSD drive, and everything works for me?
Running on a Haswell (Lynxpoint) machine with only initrd image.

I tried several times, always works, dmesg is clean.
Haswell has Lynxpoint PCH, I can try to find a PantherPoint based system a try it out with that as well.
What kind of a hard drive did you have connected? and with what filsystem? Just in case if that somehow affects the USB traffic.
