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. + +Contact information: +-------------------- + + 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. + +Bruce Tenison +btenison@dibbs.net + |
