Thanks, I appreciate it. So... Why doesn't queueing work? Rhetorical mostly, :-) but if you happen to have an answer, I'm willing to make a patch. The only guess I was able to come up with is that there's a race between uhci_submit_urb() and its callees uhci_submit_bulk() & uhci_append_queued_urb() and uhci_interrupt() and its callees that causes the "Chain of QHs and TDs" to be such that the hardware thinks the chain is done, but that the driver things the chain is running. I did see that uhci_interrupt() stops entering ie interrupts have stopped being generated, but not due to lockup since the system was fine, and I could reload my driver and have it communicate again. Please don't spend any time on this on my behalf; I've already worked around it. ..Stu ------------------------------------------------------- This SF.Net email is sponsored by Yahoo.
