To be honst - I stongly recommend that it's fixed before. I know the problem is
not related to the USB2 stack as such - However the way the problem occurs
e.g. a corruption in the ATA dma load make it far from clear that it's a USB bounce 
buffer problem and my error reports was generally ignored with the - there nothing wrong 
with the ATA code - quite correctly as it turned out but - it kept me using an old kernel
before the old brain got around to thinking about USB 

So I would love to see it fixed and I am not quite sure what the hold up is? Last time I heard
- we seemed to be caugth in between - a double "there nothing wrong with the dma code" 
and "that is the way USB works" ;-) 

I am sure there is more to it however ;-0)
