True, but is that relevant for 2.6 even?
I'd certainly think so. Periodically I notice how many
USB drivers can be "bad citizens", because they don't
let their i/o calls be interrupted like normal drivers.
It would need a change of API to use this.
It can be done easily with a "new" API call, one that gives
the option of cancel-on-interrupt. Just pass the URB in,
it returns when the urb is done.
