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).

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.

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 +Limits +====== + +You can use only a single rio500 device at a time with your computer. + +Bugs +==== If you encounter any problems feel free to drop me an email.
