Ah, good point, we can always prove "GONE" just not "PRESENT". So yes, a simple check in usb_submit_urb() for this would be a good thing to have. > Except that "GONE" can/should really mean "GONE" ... at least for USB, > as you noted, that one is no hint.

I sure hope that most of them create a new device when a new device is seen, and don't try to recycle an "old" device that was previously present. thanks, greg k-h ------------------------------------------------------- This sf.net email is sponsored by: Influence the future of Java(TM) technology.
