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 devices 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).
