+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
+ are in no way responsible for any damage that may occur, no matter how
+ 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.
+
+Bugs
+====
+
+If you encounter any problems feel free to drop me an email.
