The main things you have to worry about are acquiring the lock for both the USB device structure and the interface structure, and making sure your driver is ready to be re-probed. On the other hand, you could take a different approach to this whole problem... You could try to find out why the device is so flaky and get it fixed! Then no resets would be needed. > Sorry, if I'm irritating by asking too many questions. > I just want to understand this fully as soon as I can.
