NAME
     pxaudc - PXA27x USB Device Controller

SYNOPSIS
     pxaudc0 at pxaip?

DESCRIPTION
     The PXA27x USB Device Controller is a programmable USB client device.  It
     is also responsible for dynamically switching the physical ports between
     the USB host controller and itself by detecting whether a host or client
     cable is plugged into the connector.

     An appropriate driver can configure the device controller to operate as a
     variety of devices, e.g. an Ethernet or mass storage device, when plugged
     into a USB host.

     Currently, the pxaudc driver disables the functionality of the USB Device
     Controller and configures the physical port to be always routed to the
     ohci(4) controller.  In this mode the hardware only supports attachment
     of USB devices; it will not operate as a USB device itself.

BUGS
     There is currently no support for using the Zaurus as a USB Device, how-
     ever, it is planned for the future.
