The following figures show different ways to realize connections to an USB device using
ports U1 and U2. The example described here uses an ISP1302 for the external OTG
transceiver and the USB Host power switch LM3526-L (National Semiconductors).
For OTG functionality an external OTG transceiver must be connected to the LPC2400
device. There are two ways to connect the OTG transceiver (here ISP1302, replaces
ISP1301) to port U1:
