Thank you Alan,
here you go: http://pastebin.com/txu8M68L we included the register file

Thanks.  This confirms the reason for the problem.  It's a hardware bug
in the OHCI controller; after completing a transfer, the controller
didn't add the Transfer Descriptor to the Done List.

I'm working on a patch to detect this sort of mistake and recover from
it.  I'll let you know when it's ready for testing.
