USB2 & umass problem

[Pegasus Mc Cleaft]

Hi Current... 

	I think there may be a problem with the USB2 stack and the umass driver on 
AMD64.

	I have tried this with both a USB SATA/IDE controller and a USB flash stick. 
Both of them give similar results below. Please note that the disconnect 
message is when I pulled the device out of the USB port on the computer.
