My computer is booting just fine from the Knoppix dvd, but it's not seeing my mp3 player as a drive. I used the USB tool to confirm that the player is showing as connected (it appears as a USB CRW 2.0 device), but I'm not sure what I need to do next. The player does support 'drag & drop' and normally appears as a regular drive. I'm using version 5.1.1 on a Vista oem machine, and I've never used Linux before.
