Note that we only scan scan the bus once during the lifetime of barebox
unless the force parameter of usb_rescan is true. This is because
we currently remove all existing USB devices and reinstantiate all
USB devices found during scanning. The removal of devices is not very
well implemented. USB only works properly when the tree is scanned once.
