NAME
     pxaudc - PXA27x USB device controller

SYNOPSIS
     pxaudc0 at pxaip?
     usbf* at pxaudc?

DESCRIPTION
     The PXA27x USB Device Controller supplies bus interface functions so that
     the USB Function support driver, usbf(4), can support client-cable USB
     functions.

     The pxaudc 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, ohci(4), which supplies USB device support for many de-
     vices as described in usb(4).  If a client cable is detected, the USB
     pins are directly used by pxaudc to support USB client functionality, as
     described in usbf(4).

AUTHORS
     The initial pxaudc driver was written by David Gwynne <dlg@openbsd.org>.
     USB Client support was later developed by Uwe Stuehler <uwe@openbsd.org>
     and completed by Dale Rahn <drahn@openbsd.org>.
