No. > Doesn't urb_dequeue call set_next_interrupt? Yes, it calls set_next_interrupt. > If it does, shouldn't you see uhci_irq being called? Yes, that's what usually happens after set_next_interrupt. > Are you saying that the problem comes up only > when you disconnect during your test transmission? Yes. > Does your test involve trying to send a bulk-out message or a bulk-in? The one message I interrupt with the unplugging is always a bulk-in (meaning: read from device, right?) message. > Can you post your debugging log information, from when you start your test > up until shortly after the suspend_hc message? It is attached. There are quite a lot non-problematic URB's to and from the device before the interesting part begins. I need those to set up my device. > > - after I ran my test set_next_interrupt does not work anymore > > (triggered by "cat /proc/drivers/uhci..."). > > It shouldn't work because the controller is suspended.

The panic was caused by a call of complete() inside my drivers urb completion function. If I replug the device, uhci_irq() gets called with status = 36, uhci->state = -10. This call finally removes the urb from the queue and calls the completion handler. Unfortunately my drivers device struct is freed by then. So the panic is a consequence that my driver does not wait for all URBs it send, as it should. But, as mentioned, if I make it wait, it hangs. > If you have another USB device, you could try plugging it in and > unplugging it, to see what interrupts you get. I'm thinking that maybe > part of the trouble is caused by your test device, although I can't > imagine how. I used my USB mouse, plugged it in and unplugged. I disconnected the power of the machine beforehand and rebooted trying to make sure the controller hardware is not in some "ill" state. The result is as with my device: there is no uhci_irq call after the disconnect and still nothing after the suspend_hc. Axel.
