Please test the latest version of the drivers. Both uhci and usb-uhci have had various bug fixes. I'm sure the performance problems you've had with uhci have been fixed for a little while now.
Also, feedback about the -hcd variants would useful too since one of those will be the only ones left for 2.5.
