More testing with my PSP and the USB stick has revealed large file
transfers (e.g. 1 GB in size or more) destroy the transfer speed.
Transfers start up fast (around 20 MBps), and after a few seconds begin
to drop.

The difference being the Kingston USB stick drops to 1 MBps or less,
whereas the PSP is able to maintain a speed of around 6.5 MBps.  Both
devices connect at hi-speed (480 Mbps).

Anyone know what's going on?
