Sorry, I must have missed it.

Interesting.  It shows everything working at first, and then the device 
fails at the first large (>64 KB) read.

Is this using the EHCI driver (is it a high-speed connection)?  I've seen 
problems similar to yours on systems where the EHCI driver was trying to 
transfer data faster than the device could cope with.

Can you try running exactly the same experiment (with usb-storage 
debugging configured on) under 2.4.22?  Comparing the two debugging logs 
might provide some answers.
