USB: rename the usb misc class from "usb" to "usbmisc"

This class was not named properly years ago, and it turns out that tools like udev can't properly see the devices in this class after booting due to the fact that there is a bus with the same name in the system.

Changing this to "usbmisc" fixes this problem, and it solves the problem for the future when we want to unify classes and busses.
