7 USB Host
The PXA270 controller lacks support of controlling input devices
such as keyboard or mouse. The PXA270 on-chip USB host controller
supports one USB host interface which can also function as an OTG
interface. On the Carrier Board the USB host interfaces are connected
to a double USB host socket. Note that socked B is inactiv and must
not be used in conjunction with the phyCORE-PXA270 given the fact
that only one USB host is available. Since the USB host interface can
also operate in OTG mode it is connected to the OTG socket on the
Expansion Board as well.
