  • Hi,

    Start at the top of the troubleshooter and work down which is not a menu, its a checklist.

    Did you try the stick in another computer? Do other USB devices work in this one?

    Are you running Windows 7 Service Pack 1?

  • Hi,

    Have you tried the thumbdrive in another computer to be sure it is still viable?

    -----------------------

    Windows has stopped this device because it has reported problems. (Code 43)

    One of the drivers controlling the device notified the operating system that the device failed in some manner. For more information about how to diagnose the problem, see the hardware documentation.

    On the General Properties tab of the device, click Troubleshoot to start the troubleshooting wizard.

    Then lets refresh the USB Stack

    Control Panel - Device Manager - click anywhere in the blank/white area - then VIEW -
    Show Hidden Devices

    Now look everywhere EXCEPT USB Controllers for your device and if you find them (may have
    more than one of each) under Disk Drives you may have several - RIGHT CLICK and UNINSTALL 
    for all instances. (There may be none.)

    Control Panel - Device Manager - USB Serial Controllers - RIGHT CLICK on EVERYTHING and
    UNINSTALL all except the category itself - REBOOT - this refreshes the drive and the USB stack

    Here is a utility to help but do the above 1st.

    USBDeview is a small utility that lists all USB devices that currently connected to your computer,
    as well as all USB devices that you previously used. Run it Options and check the 1st three choices
    to see if any are there.

    You would remove all instances of the devices then reboot.
