I don't think it really takes the device offline so much as it
just stops completing requests for the device.
Like I said before, it feels more like it leaves some unhandled thing
in the device's queue from before the reset, and since that thing is
never completed, the queue never advances.
If it were offline, I would think that accessing the device would give
an immediate error saying so. Instead, it just hangs (interruptably) and
never returns, as if it is just waiting for it to complete.

That would be neat. :)

I've tried the remove/add single method.
After a bus reset, the device is so wedged that this has no effect.
The problem is NOT the physical device, but the linux driver side.
