Public bug reported:

I just bought an Asus N43JF with a USB 3.0 port, and I have a Supertalent 16GB USB 3.0 flash drive.
I'm using Ubuntu 10.10 with kernel 2.6.35-22-generic

The flash drive is correctly recognized and I can successfully copy
files, but it's very slow (max. 1.4MiB/sec).

I'm not sure which device provides the USB 3.0 port, but i think it corresponds to this line in lspci :
04:00.0 USB Controller: Device 1b73:1400 (rev 01)

Here is a typical part of kern.log I get. I would be happy to provide
more informations.
