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



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.
