		============

		A host with a USB port. Ideally, either a UHCI (Intel) or OHCI
		(Compaq and others) hardware port should work.
		A host with a USB port running a Linux kernel with RIO 500 support enabled.

		A Linux development kernel (2.3.x) with USB support enabled or a
		backported version to linux-2.2.x. See http://www.linux-usb.org for
		more information on accomplishing this.
		The driver is a module called rio500, which should be automatically loaded
		as you plug in your device. If that fails you can manually load it with

		A Linux kernel with RIO 500 support enabled.

		'lspci' which is only needed to determine the type of USB hardware
		available in your machine.

		Configuration

		Using `lspci -v`, determine the type of USB hardware available.

		If you see something like::

		USB Controller: ......
		Flags: .....
		I/O ports at ....

		Then you have a UHCI based controller.

		If you see something like::

		USB Controller: .....
		Flags: ....
		Memory at .....

		Then you have a OHCI based controller.

		Using `make menuconfig` or your preferred method for configuring the
		kernel, select 'Support for USB', 'OHCI/UHCI' depending on your
		hardware (determined from the steps above), 'USB Diamond Rio500 support', and
		'Preliminary USB device filesystem'. Compile and install the modules
		(you may need to execute `depmod -a` to update the module
		dependencies).
		modprobe rio500

		Add a device for the USB rio500::
		Udev should automatically create a device node as soon as plug in your device.
		If that fails, you can manually add a device for the USB rio500::

		mknod /dev/usb/rio500 c 180 64

		Set appropriate permissions for /dev/usb/rio500 (don't forget about
		group and world permissions). Both read and write permissions are
		In that case, set appropriate permissions for /dev/usb/rio500 (don't forget
		about group and world permissions). Both read and write permissions are
		required for proper operation.

		Load the appropriate modules (if compiled as modules):

		OHCI::

		modprobe usbcore
		modprobe usb-ohci
		modprobe rio500

		UHCI::

		modprobe usbcore
		modprobe usb-uhci (or uhci)
		modprobe rio500

		That's it. The Rio500 Utils at: http://rio500.sourceforge.net should
		be able to access the rio500.

		Limits
		======

		You can use only a single rio500 device at a time with your computer.
