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
configured 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

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

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'
