Ok - with and without acpi, I get:

Mar  9 07:42:54 neutrino kernel: usb3: unrecoverable error, controller 
halted
Mar  9 07:42:54 neutrino kernel: usb3: blocking intrs 0x10
Mar  9 07:43:20 neutrino kernel: usb3: port reset timeout

The USB key I am using is a SanDisk Cruzer Mini 256mb.  The "light" on 
the USB key never comes on (like it does in USB1.1 mode).

Let me know what I can do to help.
