|  | 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 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. |

|  | The main page for the project is hosted at sourceforge.net in the following | 
|  | URL: <http://rio500.sourceforge.net>. You can also go to the project's | 
|  | sourceforge home page at: <http://sourceforge.net/projects/rio500/>. |

|  |  | 
|  | Most of the code was written by Cesar Miquel <[email protected]>. Keith | 
|  | Clayton <[email protected]> is incharge of the PPC port and making sure | 
|  | things work there. Bruce Tenison <[email protected]> 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 <[email protected]> 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. |
