External usb 3.0 hard drive is not recognised when plugged into usb 3 port

I have an Iomega Prestige Portable External Hard Drive 1TB USB 3.0.

It works fine on windows 7 as a usb 3.0 drive.

It isn't detected on ubuntu natty 64bit, 2.6.38-8-generic.

fdisk -l cannot see it at all:

lsusb can see it:

I thought it might be that the firmware wasn't compatible with linux or something, but when booting a live image of partedmagic, (2.6.38.4-pmagic), the drive was detected fine, I could mount it and got usb 3.0 speeds (at least they double the speeds I got from plugging same drive in usb 2 ports).

dmesg in partedmagic did say something about no SuperSpeed endpoint which was an error I saw in a previous dmesg of ubuntu:

Well I have no idea what's going wrong, and I haven't had much luck from google and the forums so far. A number of unanswered threads with people with similar error messages and problems only.

Hopefully someone here can help or point me in the right direction?!
