The authors 23 are in no way responsible for any damage that may occur, no matter how 24 inconsequential. 25 26 It seems that the Rio has a problem when sending .mp3 with low batteries. 27 I suggest when the batteries are low and you want to transfer stuff that you 28 replace it with a fresh one. In my case, what happened is I lost two 16kb 29 blocks (they are no longer usable to store information to it). But I don't 30 know if that's normal or not; it could simply be a problem with the flash 31 memory. 32 33 In an extreme case, I left my Rio playing overnight and the batteries wore 34 down to nothing and appear to have corrupted the flash memory. My RIO 35 needed to be replaced as a result. Diamond tech support is aware of the 36 problem. Do NOT allow your batteries to wear down to nothing before 37 changing them. It appears RIO 500 firmware does not handle low battery 38 power well at all. 39 40 On systems with OHCI controllers, the kernel OHCI code appears to have 41 power on problems with some chipsets. If you are having problems 42 connecting to your RIO 500, try turning it on first and then plugging it 43 into the USB cable. 44 45 Contact information: 46 -------------------- 47 48 The main page for the project is hosted at sourceforge.net in the following 49 URL: <http://rio500.sourceforge.net>. You can also go to the project's 50 sourceforge home page at: <http://sourceforge.net/projects/rio500/>. 51 There is also a mailing list: rio500-users@lists.sourceforge.net 52 53 Authors: 54 ------- 55 56 Most of the code was written by Cesar Miquel <miquel@df.uba.ar>. Keith 57 Clayton <kclayton@jps.net> is incharge of the PPC port and making sure 58 things work there. Bruce Tenison <btenison@dibbs.net> is adding support 59 for .fon files and also does testing. The program will mostly sure be 60 re-written and Pete Ikusz along with the rest will re-design it. I would 61 also like to thank Tri Nguyen <tmn_3022000@hotmail.com> who provided use 62 with some important information regarding the communication with the Rio. 63 64 ADDITIONAL INFORMATION and Userspace tools 65 66 http://rio500.sourceforge.net/ 67 68 69 REQUIREMENTS 70 71 A host with a USB port. Ideally, either a UHCI (Intel) or OHCI 72 (Compaq and others) hardware port should work. 73 74 A Linux development kernel (2.3.x) with USB support enabled or a 75 backported version to linux-2.2.x. See http://www.linux-usb.org for 76 more information on accomplishing this. 77 78 A Linux kernel with RIO 500 support enabled. 79 80 'lspci' which is only needed to determine the type of USB hardware 81 available in your machine. 82 83 CONFIGURATION 84 85 Using `lspci -v`, determine the type of USB hardware available. 86 87 If you see something like: 88 89 USB Controller: ...... 90 Flags: ..... 91 I/O ports at .... 92 93 Then you have a UHCI based controller. 94 95 If you see something like: 96 97 USB Controller: ..... 98 Flags: .... 99 Memory at ..... 100 101 Then you have a OHCI based controller. 102 103 Using `make menuconfig` or your preferred method for configuring the 104 kernel, select 'Support for USB', 'OHCI/UHCI' depending on your 105 hardware (determined from the steps above), 'USB Diamond Rio500 support', and 106 'Preliminary USB device filesystem'. Compile and install the modules 107 (you may need to execute `depmod -a` to update the module 108 dependencies). 109 110 Add a device for the USB rio500: 111 `mknod /dev/usb/rio500 c 180 64` 112 113 Set appropriate permissions for /dev/usb/rio500 (don't forget about 114 group and world permissions). Both read and write permissions are 115 required for proper operation. 116 117 Load the appropriate modules (if compiled as modules): 118 119 OHCI: 120 modprobe usbcore 121 modprobe usb-ohci 122 modprobe rio500 123 124 UHCI: 125 modprobe usbcore 126 modprobe usb-uhci (or uhci) 127 modprobe rio500 128 129 That's it. The Rio500 Utils at: http://rio500.sourceforge.net should 130 be able to access the rio500. 131 132 BUGS 133 134 If you encounter any problems feel free to drop me an email. 135 136 Bruce Tenison 137 btenison@dibbs.net
