The PXA255 controller lacks support of controlling input devices
such as a keyboard or a mouse. Therefore the Philips ISP1362 USB
host OTG (on the go) controller has been integrated on the phyCORE-
PXA255. This controller supports two USB host interfaces, whereby
one can function as an OTG interface. On the Development Board the
USB host interfaces are connected to a double USB host socket. The
first USB host interface can also operate in OTG mode and is also
connected to an OTG socket on the Expansion Board. The first USB
host interface can only be used either on the Development Board in
OTG mode or on the Expansion Board.
