For people who have been experiencing very sporadic problems with USB 2.0 
devices under Linux it has recently been revealed to me that the EHCI 
stack in Linux did not support zero-length writes to an endpoint up until 
the very recent 2.6.16.

It appears to work fine on UHCI/OHCI though, so speeding down is an 
option, ur just upgrade the kernel.

This problem only appear when downloading tracks to a USB 2.0 device, 
something like every n:th file will fail and lock the device.
