Requirements
============
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.
modprobe rio500
'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).
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.
