You use usb_register_dev(). And you do that in your probe() method,
not in your init() method. Init() has usb_register(), probe() has
usb_register_dev(). Simplified of course. There are other ways, but this
is the simplest way. usblp is a nice example.
You then open your device using the open(2) syscall.
