Hi, I sent this mail already yesterday but didn't receive it on the list so I guess something went wrong. Sorry if someone receives it twice.

Is that right? I don't know if the implication 'since' is true but yes remove_pending_qhs() isn't getting called for my URB and the URB isn't dequeued until after the disconnect. > But if your device is the only one attached the volume of messages won't > be too high.

I have the feeling I am getting closer: uhci_irq() is not called after the unplug (at least not for about 10 seconds). Is no the time to suspect the hardware or is there more to check with the driver? can I verify somehow that uhci_set_next_interrupt(uhci) is working? If you would guide me like this even further, I'd be really happy. Thanks, Axel. ------------------------------------------------------- This SF.net email is sponsored by: Perforce Software.
