So it seems MS has a problem with " usb device not recognized in windows 7 ". A Google search will find no real solutions to the problem. I haven't found one hear ether. How can I have a handful of flash drives and external hard drives that will not work on only 2 Win7 systems that I know of ,yet work on others ? I never needed to download drivers from anyone to make them work on any other OS . I just plug them in and the work ... THE 1st TIME... not after trying all things that don't.  This is something that needs a REAL FIX. I should not have to pay Tech Support to find out why. This is clearly an OS Win7 problem. Thanks     This is real FRUSTRATING

Hi DJBigBang,

1. Have any USB or external drives worked on your computer? 2. What is the make and model of your computer?

As all the hardware devices have drivers associated similarly USB devices also have it. Sometimes proper drivers do not get detected after the initial installation so reinstallation of the drivers helps resolve the issues.

You may check after uninstalling and reinstalling the USB drivers if you are able to connect. You may disconnect all USB devices and then perform the following steps:

1.     ClickStart, and then click Control Panel.

2.     ClickSystem and Maintenance, click System, and then clickDevice Manager.

Note If Control Panel is in Classic View, double-clickSystem, and then click Device Manager.

If you are prompted for an administrator password or for a confirmation, type the password, or clickAllow.

**3.**In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the Host Controller, click "Uninstall" and click "OK".

Check if at all there is an exclamation mark along the driver, it suggests issues with the driver installed.

4.     Repeat the step 2 to uninstall all items under "Universal Serial Bus controllers".

Then, restart your computer and Windows 7 will reinstall all USB controllers automatically.

If you still face the same issue then you may check for the updated USB device drivers using windows update. Refer to the below link for assistance–

If the issue sill persists I would request you to check for chipset driver updates which you can get at the manufacturer website. The chipset drivers normally incorporate USB controller drivers as well.

Hope this helps.

Thanks,

Hello DJBigBang,

There is an old Windows XP KB article that was recently updated with multiple steps to resolve these types of issues. The KB covers Windows XP, Windows Vista and Windows 7 with step by step methods. See if this helps.

    Here are the common solution to fix USB Device not recognized errors. First thing you should do is update your USB drivers to the latest version from your motherboard manufacturer. This usually fixes the problem for most users. You can either search the manufacturer’s website and download/install the current driver, or you can run a recommended driver update program. After checking your drivers are updated, try the following solutions.

    1. Unplug your computer. Don’t just turn it off with the power button, you need to actually unplug the cable from the power supply for at least 1 minute. This often resets your USB hub on your motherboard.
    2. Remove the battery. If you computer is a laptop, remove the battery for at least 2-3 minutes before plugging it back in and restarting Windows.
    3. Uninstalling root hub drivers. If steps 1 and 2 above do not work, try the following:
      • Unplug all USB devices from your computer.
      • Go to Device Manager in Windows 7 or Vista**.**
      • Uninstall EACH Root Hub USB Driver.
      • Power off your computer and UNPLUG THE CABLE FROM THE POWER SUPPLY, just don’t shut it down.
      • Reconnect the power supply cable and turn your computer on after 2-3 minutes.
      • Reconnect each external USB device. (i.e. mouse, keyboard, thumb drive, etc.)
    4. If you still have issues and cannot get rid of “USB device not recognized” error messages you can try disabling USB 2.0 devices which should remove the error message and “fix” the problem (although it’s more of a band aid then an actual solution)  but your USB devices will now run at the slower USB 1.1 speed.
