+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:
+
+W A R N I N G:
+--------------
+
+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 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 thats 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.

+   The main page for the project is hosted at sourceforge.net in the following
+   address: http://rio500.sourceforge.net You can also go to the sourceforge
+   project page at: http://sourceforge.net/project/?group_id=1944 There is 
+   also a mailing list: rio500-users@lists.sourceforge.net

+Authors:
+-------
+
+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.

+ADDITIONAL INFORMATION and Userspace tools

+
+
+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.
