Okay, it's not mass media. It's a program that makes my Palm SD card appear as mass media. Here's the problem. It worked fine on two seperate computers the first time I plugged it in. After the first time, it stopped working. Every time I plug it in, I get the following error in /var/log/messages:

Nov 15 18:22:59 cayanne kernel: usb 1-1: new full speed USB device using address 7
Nov 15 18:23:00 cayanne kernel: usb-storage: probe of 1-1:1.0 failed with error -1
Except that the using address is incremented by one everytime I replug it in. I can't find what error -1 is.

Anyone have any ideas?
