Overview

|
|
This README will address issues regarding how to configure the kernel
|
|
to access a RIO 500 mp3 player.
|
|
Before I explain how to use this to access the Rio500 please be warned:
|
|
|
|
.. warning::

Please note that this software is still under development. The authors

|
|
inconsequential.

It seems that the Rio has a problem when sending .mp3 with low batteries.
|
|
I suggest when the batteries are low and you want to transfer stuff that you
|
|
replace it with a fresh one. In my case, what happened is I lost two 16kb
|
|
blocks (they are no longer usable to store information to it). But I don't
|
|
know if that's normal or not; it could simply be a problem with the flash
|
|
memory.
|
|
|
|
In an extreme case, I left my Rio playing overnight and the batteries wore
|
|
down to nothing and appear to have corrupted the flash memory. My RIO
|
|
needed to be replaced as a result. Diamond tech support is aware of the
|
|
problem. Do NOT allow your batteries to wear down to nothing before
|
|
changing them. It appears RIO 500 firmware does not handle low battery
|
|
power well at all.
|
|
|
|
On systems with OHCI controllers, the kernel OHCI code appears to have
|
|
power on problems with some chipsets. If you are having problems
|
|
connecting to your RIO 500, try turning it on first and then plugging it
|
|
into the USB cable.

-------
|
|
|
|
Most of the code was written by Cesar Miquel <miquel@df.uba.ar>. Keith
|
|
Clayton <kclayton@jps.net> is incharge of the PPC port and making sure
|
|
things work there. Bruce Tenison <btenison@dibbs.net> is adding support
|
|
for .fon files and also does testing. The program will mostly sure be
|
|
re-written and Pete Ikusz along with the rest will re-design it. I would
|
|
also like to thank Tri Nguyen <tmn_3022000@hotmail.com> who provided use
|
|
with some important information regarding the communication with the Rio.

Requirements
|
|
============
|
|
|
|
A host with a USB port. Ideally, either a UHCI (Intel) or OHCI
|
|
(Compaq and others) hardware port should work.
|
|
|
|
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.
|
|
|
|
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).
|
|
|
|
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
|
|
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.
