This change allows the compiler to handle callbacks resolution. Callbacks now must be implemented on the class that extends PUSBListNode and this is forced by compiler by means of pure virtual methods. Also the calls to HID.interface() and HID.endpoint() can now be simplified to interface() and endpoint() respectively since the methods are no more static.
