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:

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 running a Linux kernel with RIO 500 support enabled.
|
|
|
|
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
|
|
|
|
modprobe 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
|
|
|
|
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.
|
|
|
|
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.
