 .Nd PXA27x USB Device Controller
 .Sh SYNOPSIS
 .Cd "pxaudc0 at pxaip?"
+.Cd "usbf* at pxaudc?"
 .Sh 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.
-.Pp
-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 only ethernet 
-.Xr cdcef 4
-is supported .
+The PXA27x USB Device Controller supplies bus interface functions
+so that
+the USB Function support driver,
+.Xr usbf 4 ,
+can support client-cable USB functions.
 .Pp
-Currently, the
+The
 .Nm
-driver configures
-.Xr usbf 4
-and 
-.Xr cdcef
-usb client drivers on boot and enables host mode
-.Xr ohci 4
-and probes the usb bus when a host cable is connected.
+driver is able to detect the presence of either host or client cables.
+If a host cable is detected, the USB pins are routed to
+the USB host controller,
+.Xr ohci 4 ,
+which supplies USB device support for many devices as described in
+.Xr usb 4 .
+If a client cable is detected, the USB pins are directly used by
+.Nm
+to support USB client functionality, as described in
+.Xr usbf 4 .
