From: Jan Kiszka <jan.kis...@siemens.com> When creating an USB device the old way, there is no way to specify the target bus. Thus the warning issued by usb_create makes no sense and rather confuses our users.
Resolve this by passing a bus reference to the usbdevice_init handler and letting those handlers forward it to usb_create.
