    Ubuntu Doesn't Detect Media in USB Card Reader

    I have a Digital Concepts CR-75 51-in-1 USB card reader. When I plug it in by itself, I get four new empty partitions that show up (labeled 'Myson'). However, when I insert an SD card or mini SD card into the appropriate slot, the partition where that card would mount at seems to disappear. The other unused ones still show up, but obviously are inaccessible because of lack of media.
    I have the driver disc for Windows, but I can't find Natty drivers anywhere. I might also add that on Windows, the read/write LED lights up after a moment, but on Ubuntu it only gives power to it. XD cards seem to work for some reason.

    I also ran into something interesting when booting the GParted Live disc, but I can't recall the error at the moment. I can remember that it shows a timeout error and tries to kill some process, but fails until I remove the device.

    This is a serious inconvenience, as I'm making backups of some console games onto my hard drive and transferring files over the router is time-consuming, confusing, and slow. Any help would be much appreciated.

    Mega bump. Why do I always seem to get the issues that nobody cares about? I've had at least three individual threads on separate issues that no one has bothered to reply to.

    I Second that request. I have the same issue with the same card reader. Not sure what to do here.

    This is how the device shows in USB. So it is being picked up, however it does not seem to automount..

    Re: Ubuntu Doesn't Detect Media in USB Card Reader

    Finding out a little more about this device..

    Code:
    routh@routh-laptop:~$ ls -l /dev/disk/by-id/usb*
    lrwxrwxrwx 1 root root 9 Apr 12 15:51 /dev/disk/by-id/usb-Myson_CS8819A3-116_0_100-0:0 -> ../../sdb

    It seems to load 4 virtual hard drives for mounting the cards.. however attempting to them manually tells be that there is no disk on any of them.
