Realistically, the sleep 5 isn't sufficient in other cases.  We should
probably instead do something and verify that /proc/bus/usb/devices is
stable (ie, that two checks one second apart haven't changed) similar to
what anaconda does in anaconda/loader2/usb.c:sleepUntilUsbIsStable()

This will lead to a shorter sleep on "normal" systems and more correct
behavior on systems with a longer USB device tree to enumerate.
