NAME

     urio -- USB driver for the Rio MP3 players

SYNOPSIS

     To compile this driver into the kernel, place the following line in your kernel configuration file:

	   device urio

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   urio_load="YES"

DESCRIPTION

     The urio driver provides support for Rio MP3 players from Diamond MultiMedia which attaches to the USB port.  The urio device must be config-
     ured in the kernel, along with usb and one of the uhci or ohci controllers.

     Subsequently, the /dev/urio0 device can be used by the Rio userland applications.

HARDWARE

     The following devices are supported by the urio driver:

     o	 Diamond MultiMedia Rio 500
     o	 Diamond MultiMedia Rio 600
     o	 Diamond MultiMedia Rio 800

FILES

     /dev/urio0
		blocking device node

EXAMPLES

     The following line in the kernel configuration file adds the urio driver to the kernel:
	   device urio

     To download a song over the USB connection into the Rio using the rio_add_song(1) utility (see the SEE ALSO section):
	   rio_add_song /usr/local/MP3/TracyChapman/02-Fast-Car.mp3

SEE ALSO

     ohci(4), uhci(4), usb(4)

     The Rio 500 SourceForge Project Web Page, http://rio500.sourceforge.net/.

     The Rio500 tools from SourceForge are the actual userland tools used to download, format or rename songs on players.  When compiling these
     tools, the following pre-build configuration command will ensure that rio_usb.h is available in the include path and that the device used is
     /dev/urio0:

	   CFLAGS="-I/usr/include/dev/usb" ./configure 
	       --with-devicepath='/dev' --with-deviceentry='urio0'
