   Hi,

The only fix I can think of is allocating a receive buffer inside
the UHCI code for read transfers, and copy the result over to the
guest memory when we are re-scanning the schedule, encounter the
completed td and are going to signal its completion to the guest.

I could take a shot at writing a patch with the proposed fix, but I
was sort of waiting on a reaction on the proposal first.

Gerd what do you think of my proposed fix ?

That should fix it indeed.  Yes, for uhci we can live with the overhead,
it's low bandwidth anyway.  No, I don't have a better idea.  Patch is
very welcome.

Ok, I've put this on my todo list, I expect to be able to start working
on this next Tuesday (and hopefully will finish it in 1 day).

Regards,

Hans
