OK, you asked for it - no fair complaining about the email wart that I
can do nothing about.
It happens.

Is this a USB thing, or an input thing?
I'm not sure I understand the question. The problem is in the
usbtouchscreen kernel module, which is an input module.

The problem is NOT at the X layer (read: user space), but in the kernel
driver.

Did that answer the question?
The question was asked of the USB and input developers ;) It's unclear
(to me) which subsystem would need fixing to make this work properly.
I suppose this is device-specific and will have to be worked around in
the driver buy resubmitting request a few times until it "sticks".
Hmm, I take it back... the message comes from the IRQ routine; that
means we were able to submit IRQ at least once. Plus we do send a
few control messages for mtouch. So I don't understand why it would
start returning -ENODEV out of sudden.
