    Question DSE A5148 16GB Multimedia MP3 Player

    I have recently bought a new **** Smith Electronics 16GB Multimedia MP3 Player (A5148) and am unable to get it to run under Kubuntu 9.10 64bit edition. I am able to charge the device from the USB port and I can also use the device on the Vista Ultimate 64bit computer (after the usual M$ stuff around and several reboots).

    I have read that the A5146, which is the 8GB version of the one that I have, works very well in Ubuntu 8.10 and shows up as a USB drive. I have spoken to DSE Help and they weren't any, other than to say that the drive only mounts under their nominated OS and is nothing like a USB storage device, which I know is rubbish. I tried searching for it using lsusb, but it hangs the process and I have to kill it.

    I was wondering if there is anyone out there who has any idea how to mount this drive, even if I have to run a 32bit distro. Please feel free to let me know if you require any other information.

    Cheers,

    Paranoid Tux

    I too have had this device given to me. Today I took it to the store and tried it on their Vista machines. It mounts _sometimes_ on vista and uses the standard usb storage driver.
    I pulled the hardware ID's off it:

    Code:
    VID_IE74&PID_4621&Rev_0000
    When pluging in I get the following:
    Code:
    Initializing USB Mass Storage driver...
    scsi2 : usb-storage 5-7:1.0
    usbcore: registered new interface driver usb-storage
    USB Mass Storage support registered.

    sd 2:0:0:0: [sdb] 32296960 512-byte logical blocks: (16.5 GB/15.4 GiB)

    usb 5-7: reset high speed USB device using ehci_hcd and address 9
    usb 5-7: reset high speed USB device using ehci_hcd and address 9
    usb 5-7: device descriptor read/64, error -110
    I have tried with the latest (at time of writing) kernel, 2.6.28-rc2 with no improvement.

    Given the nature of the error (i.e. it appears to be a hardware fault) I consider this a kernel bug and will follow it that way.

    (Also tried on Fedora, Opensuse, Mint, and Debian.)

    Can someone confirm that the 8Gig device works. If so I will go and swap it 8)

    Cheers.

    It is now fixed upstream, thanks to Alan Stern and the linux-usb team:

    Note that for kernels before 2.6.37, the USB_* flag names were called
    US_* instead. The patch will have to be adjusted to apply to the
    earlier stable kernels.
