Hi Pavel,
There needs to be some load on the usb. I use
rsync-over-bt-over-gprs/umts.
you told me before and I believe you. This driver is not in its
best shape.
Weird thing is that I never got it re-produced. If you find the
real cause.
That would be great.
The cause seems to be hci_usb_close() racing with the USB core and
completion handlers...
It could be easily fixed by just not freeing the urbs during
disconnect (introducing very very slow memory leak). Would that be
acceptable?
I don't think so.
Have you ever tried btusb driver? That code is a lot cleaner and
it uses
USB anchors for the queued URBs (no home grown broken URB queues).
I wish I knew about this one earlier. Yes, it seems to work for me.
Does this mean you are not fixing hci_usb anymore ;)
I'm not sure what's next, as hci_usb is still in opensuse11...
the goal should be improve btusb. Especially add all the needed quirks
from the hci_usb driver to it. I have a patch for it, but I need to
reverse the HCI_RESET logic.
However if you have hci_usb patches, send them, I will review them and
David will happily apply them I guess.
Regards
Marcel
