    [SOLVED] USB flash drive not recognized


    I'm running Ubuntu 10.04, and am having trouble getting it to recognize my flash drive in the USB port. It showed up once in the Computer - File Browser and I was able to mount it and access the files on it, but since then it doesn't show up. It works fine on my Ubuntu 9.10 distro. I get the same results on both distos when I run #lsusb# The results are:

    Bus 001 Device 002: ID 05dc:a701 Lexar Media, Inc. JumpDrive FireFly
    Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Can anyone tell me how to fix things so I can access the flash drive?

    Thank you very much. The Forum has been a great help to me.

    Does fdisk -l command list USB Drive?
    Plug-in stick and execute this in Terminal :
    tail -s 3 -f /var/log/messages
    sudo fdisk -l

    It is amazing what you can accomplish if you do not care who gets the credit.

    USB flash drive and DVD drive recognized intermittently


    Thanks for the reply and the helpful info. This morning the flash drive worked for a while, then a little later, after installing some Movie Player apps, the system quit recognizing it, and now also doesn't recognized the DVD drive. I think when it's not recognizing one, it also won't recognized the other. The last time I booted the system, it wouldn't recognized the USB wifi device. I rebooted again, and then the wifi device wast there. Here's the output from the code you gave me with the flash drive plugged in:

    Problem solved

    I think the problem is solved, at least for now. I installed the first OS update, and so far the system now recognizes the flash drive.
