No, currently I don't even depend on gnome mounting it. I don't run a 
desktop. I just mount it manually in the single user mode with "mount" 
(eliminates variables that is). If I mount it, it first looks ok. Then I 
write a file on it. Still looks ok. Then I call "sync". That finally 
locks it up with the 2.6.32 kernel, not on 2.6.31. For the .32, it just 
sits there, after probably twenty seconds, it times out, complains that 
it can't write, then dies away. Works just nicely with the .31 kernel.

Thus, at this time, I guess I would need to know more about how a write 
reaches the ehci module, and how the configuration from there works.

Sorry, but this isn't quite as simple as I thought.

Thanks,
	Thomas
