How to Fix USB Device Not Recognized on Windows 8.1

Many times when we insert USB drives into the USB port Windows shows up a message that USB is not recognized by Windows 7 or even Windows 8.1 as it has malfunctioned. This error can happen if you insert mouse, pen drives, mobile phones or even digital cameras and as a result of this you will not be able to use it. Sometimes even after reinstalling the drivers, you still face this issue.

How to Solve the issue? We will list out some of the steps you can perform to fix this issue.

USB-device not recognized

Apparently there are many ways to try solving this issue.

METHOD 1.

Click Start-> Run ( or use Win+R) and type Devmgmt.msc, and this will open up the Device Management. Click to select your computer as the location for the scan. Right click on the computer and click Scan for hardware changes, you can also do this from the actions menu.

Scan for hardware changes

If your USB device is not recoginized, it will be listed as unknown here. Most probably Windows will be able to detect the problem and recognize your USB drive. In case you still face the issue, try method 2.

METHOD 2:

Click Start-> Run (or use Win + R), type Devmgmt.msc, opening the Device Management. Expand Universal Serial Bus controllers and right click on the USB drive which is showing error or not recognized issue.

Select properties from the right click menu and select the Power Management tab. Click to clear the “Allow the computer to turn off this device to save power” check box, and then click OK. Now from the the Action menu, click Scan for hardware changes as mentioned in STEP 1.

Power Management

Windows will again start scanning for changes and it should be able to find out USB device.

METHOD 3: 

Click Start-> Run ( or use Win+R) and type Devmgmt.msc, and this will open up the Device Management. You will be seeing the USB device as “unknown device” in the device management. Double click on this entry and this will open the properties tab. Here select the Driver tab and click Update drivers and see if there is an update available. Many times this could solve the issue.

METHOD 4:

If you are still not able to solve the problem, power off the machine, disconnect the USB, pull the battery (in the case of a laptop) or remove the power connection to PC (in the case of the desktop), and let it sit for about 10-15 minutes. Restart your PC and it should be able to detect the USB. In this case, you are actually restarting the motherboard by removing the power and this should solve the issue in most of the cases.

If these options do not work, probably the only solution is to recover the data from the USB drive. You can try connecting the USB pen drive to another PC and see if it detected. You can also try Wondershare data recovery tool which helps in recovering data from pen drives. You can recover over 550 file formats including documents, photos, emails, and videos.

      This is not Windows 7 alone, it would work with Vista and XP as well.

    The Windows error “USB Device Not Recognized” means that the computer may not recognize the USB device plugged into the computer. When this issue occurs, the USB device may or may not be listed in Device Manager as an unknown device.
    Causes
    This issue mainly occurs because of several factors, which may include the following:
    • Host controller hardware malfunction
    • Incorrect USB driver versions
    • No support for USB 2.0
    • Additional system hardware or configurations that may change the timing
    • Attached hubs
    • Attached devices
    Solutions
    To work around the above issues, one of the below solutions could prove helpful:
    • Unsecure or Loose Connection
    Unplug the presently connected USB device (if any). It is quite possible that the connection is not secure and has become loose. Re-plug the USB device tightly and firmly into the USB port. This is one of the most common reasons for an error in detecting a USB device.
    • Scan for Hardware Changes in Device Manager
    Use the Device Manager to scan for new and recently installed hardware. From the Start menu, select the Run option. In the pop up box, type in Devmgmt.msc and then click Ok. From the Action menu, click Scan for hardware changes. This will make Windows scan & recognize any new devices that are installed. Now, close all opened device managers and control panels. Now, follow the above step and see if your computer detects the USB device.
    • USB Hub Power Management
    Disable power management of the USB hub. To disable the power management on the USB hub, follow these steps; Click Start, and then click Run. Type devmgmt.msc in the popup box, and then click Ok. Expand the Universal Serial Bus Controllers’ node, and then follow these steps for each USB Root Hub that is listed.

    1. Right-click the USB Root Hub and then click Properties.
    2. Click the Power Management tab.
    3. Click to clear the Allow the computer to turn off this device to save power check box, and then click Ok.
    Note: If you perform the following procedure on a laptop computer, you may reduce the battery life.
    Sometimes, simply unplugging the USB device and turning off the computer for twenty minutes and then restarting may solve the issue. If none of the above options have solved the problem, check the manufacturer’s website for new driver information. It is possible that your drivers need to be updated. There could also be a possibility of hardware failure, which needs to be checked by a hardware expert.
    I Hope this helps someone fix that pesky “USB device not recognized” Windows error!

    Any comment for someone who has tried all of these items and more and is still having the problem? All of my USB devices were working fine until this week. Now, they can be charged when plugged in but the computer will not interface with them (like the Itouch). The good news is that I have more than one device and it is doing the same thing to each and it happens no matter which of the USB ports I plug into.

    This is all very well for devices (keyboards, mice etc) but not USB sticks. These have a high failure rate and consistently come back with Unknown Device severely limiting the options (and tabs! – no power management) you have to deal with it.
    “Windows has stopped this device because it has reported problems. (Code 43)” is reported on many different machines. All the workarounds above (while possibly successful on other devices) seem not to work with USB memory sticks. I just wish the device would report (in a readable format) *what* problems it was having!

    Linking them to multiple websites, and. Unless you work at a beach of course.

    This is obviously so that your customers can click through
    to your website if they are interested in making a purchase or learning more about your products
    and services.
