- 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
- http://rio500.sourceforge.net/
- 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.
- BUGS
- If you encounter any problems feel free to drop me an email.
