I don't know if you're aware of the Turbo-Mode USB patch from M$.

It is basicly a USBSTOR.sys driver whith a configurable MaximumTransferLength.
The value can be increased from the default 65535 (64 KB) to 2097120 (2 MB).
Which gives a nice speed boost for files larger than 64k.
I was wondering, what MaximumTransferLength you use in your driver and if you could maybe increase it?
