    Ubuntu not detecting media devices?


    Well, i don't really think this needs an introduction. I want to backup all my data onto my MP3 Player, so I plug my MP3 Player up to my computer using the USB Ports.

    However, Ubuntu doesn't detect it.
    Ubuntu DOES detect my litte 512Mb USB stick, even though it's using the same port.

    Yes, my MP3 Player & cables all work (On windows that is)
    And I know my MP3 player is capable of having all of this backed up as I've backed up all my data before from a windows OS...

    So it all boils down to - How come Ubuntu isn't detecting my MP3 Device?

    What type of MP3 player is it? Is it normally detected as a hard drive or is it managed using a program?

    With windows, it was noted as an external hard drive, as I could explore it and such, it does come with software but it's not vital for it to run, or the drivers.

    It's a 30GB Creative Zen, if that's any help.

    Also, I'm running Linux off a live CD, so I can't use any other CD at the same time.

    Yeah the Zen should work. Right after you plug it in can you run the following command in the terminal and post back the last 10-15 lines?
    Code:
    dmesg

    You're not alone

    I've used debootstrap and configured my own debian system. on an amd64 machine. I've spent a few days trying to work out why I get:

    ata1: command Oxca timeout, stat Ox50 host_stat Ox24
    ata1: status=Ox50 { DriveReady SeekComplete }
    sda: Current: Sensekey: No Sense
    Additional sense: No additional sense information
    Info fld=Ox####

    Consistently repeated (the # (= numbers) increase). I think it must be a linux driver error as the above message applies to 2.17.0 and 2.17.6 kernels. My 2.6.16.5 kernel gave:

    ata1: command Ox35 timeout, stat Ox50 host_stat Ox24

    etc

    Knoppix doesn't produce any error despite being left running for a few days, whereas my debian crashes after an hour (before crashing I can write multiple times and to multiple location on my hard-drive as though everything worked perfectly).

    Anyway my next step is to try cross compiling linux from scratch to see if that suffers, once I trawl some more through the web.
