Just different, unfortunately. The error is clearly in the hardware and  
there isn't much the USB subsystem can do about it since the EHCI driver  
just programs the controller and the actual timing depends on the  
controller. At which point the difference springs into existence is  
something I haven't understood yet and nobody was able to tell me.

We were talking to the Linux USB stack developers a few weeks ago but  
there was no conclusion about this particular problem.

Cheers,
Martin
