Hi all.

For some reason, uhci is _really_ slow with usb-storage for my Archos USB
harddisk. I did a simple test comparing uhci and usb-uhci:

# time dd bs=1M count=5 if=/dev/scsi/host1/bus0/target0/lun0/disc of=/dev/null

with uhci: 1:25.83
with usb-uhci: 0:07.07

The transfer rates work out to about 61 Kbyte/s for uhci and 741 Kbyte/s for
usb-uhci.

This is vanilla 2.4.14 on a PIII/666 with a VIA chipset.
