hello,
Remember when i asked about rescheduling urb in the completion routine ?
I had a problem with it.
I don't know if it is me or usb-uhci. ( probably a bit of both..)
The problem arises when i start resubmitting the urb during it's
completion.
This seemed to cause an interrupt each frame.
what error does it report in such a case?
I return on ENODEV, process the urb when the lengthfield is not 0 and
the status isn't EINPROGRESS.
(This is probably too generic, but i don't know what the status field is
at successfull completion. ( 0 ?))
anything else results in a rescheduling of the urb.
What i was wondering is why the usb-uhci reports a stalled endpoint ?
Isn't it capable of detecting a removed device and return -ENODEV ?
anyway, the usb-uhci log is at the end, it ends when my system
hardlocks.
can this be related ?
J.
