URIO(4)		       FreeBSD Kernel Interfaces Manual		       URIO(4)

NAME
     urio -- USB driver	for the	Rio500 MP3 player

SYNOPSIS
     device urio0

DESCRIPTION
     The urio driver provides support for the Rio500 MP3 player	from Diamond
     MultiMedia	which attaches to the USB port.	 The urio device must be con-
     figured in	the kernel, along with usb and one of the uhci or ohci con-
     trollers.

     Subsequently, the /dev/urio0 device can be	used by	the Rio500 userland
     applications.

FILES
     /dev/urio0
		blocking device	node

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

     The following commands create the device node in the /dev directory:
	   cd /dev
	   sh MAKEDEV urio0

     Finally, to download a song over the USB connection into the Rio500 using
     the rio_add_song(1) utility (see the SEE ALSO section):
	   rio_add_song	/usr/local/MP3/TraceyChapman/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'
