    Lexar Jump Drive Wouldn't Work in the Front USB Ports

    USB not Recognized Sometimes Lexar jump drives will not work in the front panel USB ports. The reason is the fact that these front panels are passive ports. So they don't provide initialization power which is required for some USB drives. Due to low power supply, the USB drive may not work and you will identify the problem as USB not recognized error. Therefore you have to use a USB port in the back of your computer to check whether your USB flash drive works or not.

    Hardware Errors in the Motherboard or USB Ports

    If your Lexar jump drive is not recognized after using USB ports in the back panel of the computer to insert the jump drive, then there might be hardware issues associated with it. Another solution is changing the jumper of the USB in the motherboard. First you'd better to clean your motherboard to make sure cables are properly fitted. If you have no experience, you have to ask for help from a technical person. Because of the frequent use of USB devices, your hardware may have been worn out, causing it to not be recognized.

    There might be a failure in your jump drive meaning it is not detected. So you must try attaching it to another computer (maybe one of your friends) to see whether it is recognized? If the problem still exists, there is a chance that your jump drive is faulty.

    USB Not Recognized - XP and Vista

    There is another case where the problem may occur. Once you complete your work with the jump drive, sometimes you might remove it without clicking the "Safely Remove Hardware" icon in the Windows operating system. In this case, when you inserted the same USB flash drive or another, Windows may not recognize your drive. The reason is when you use the "Safely Remove Hardware" icon to tell Windows that you want to remove the USB flash drive, Windows tell itself that the drive is not connected and displays a message saying that you can safely remove it. But if you didn't use this "Safely Remove Hardware" option, Windows won't properly turn off its internal settings for the jump drive. That means when you inserted the pen drive again, Windows won't detect it. Here the solution is easy. You just need to reboot Windows and the problem will be solved.

    Update Your BIOS

    Sometimes computers with older motherboards might not work with newer USB flash drives. In this case you have to check your BIOS settings and see whether the USB options are disabled. Different BIOS manufacturers have different terms for this. This is a very risky operation. So you have to get the advice of an experienced person to resolve the issue if the problem is with your BIOS settings. You can update your BIOS to the latest version to resolve the issue. But it is also a very risky and advanced task. If you are not familiar with it, get the assistance.

    Driver Conflicts and Issues

    USB drives may be not recognized due to driver issues or driver conflicts in your operating system. When you install software like Daemon Tools, Nero, and Alcohol (virtual drives and burning tools) you may have to face driver conflicts. If this is the case, try uninstalling the newly installed software. If you installed service packs for Windows XP or Windows Vista, it also might cause the USB not recognized problem. To resolve the problem first you need to see whether the jump drive is displayed in the Disk Management utility of Windows. Then you have to change the drive letter of the jump drive. Here is how you have to resolve the problem in both Windows XP and Windows Vista:

    1. Go to Start > Control Panel > Administrative Tools > Computer Management (Need administrative rights to access) > Storage
    2. Now open Disk Management and see whether your jump drive is listed there.
    3. If it is listed then right click on the USB flash drive and click Change Drive Letter and Paths.
    4. Now a Window will be opened and click on the Change button.
    5. Select a drive letter and click OK.
    6. Click Continue on the confirmation.

    Now check whether your jump drive is detected. If still doesn't work try rebooting the computer. If your Lexar jump drive is still not recognized, this also might be helpful to resolve the issue.
