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' AUTHORS
