Problem
=======
When turning on the laptop and during POST and GrUB loading, all ports
on the hub are enabled. During the USB initialization phase, when the
hub is detected, shortly all ports become disabled, then turn on again
(uhci_hcd detects the lo-speed ports). Upon initialization of ehci_hcd
however, the ports are disconnected again (for good):
Use uhci_hcd or ehci_hcd, but never both at the same time.
ehci_hcd will work with all lo-speed ports, so uhci_hcd is then no needed.
