	It seems to be rather better here - no error messages in the logs
and writing to my mp3 player goes at 1.5-1.8 MB/sec while reading runs at
4-5MB/sec. Nowhere near the limit of USB 2.0 but certainly faster then 1.x.
I suspect the device as being the limiting factor but I could be wrong. This
with a VIA VT6202 controller (on an Asus A8V motherboard).
