Why would I see this problem?

The exact cause to this problem varies on different combinations of computer environments. It could be caused by malfunctioned USB ports, USB controllers bugs, or outdated, missing or faulty USB ports.

As mentioned, the exact cause could be very different in different situations, but there are some general resolutions that you should try before you turn to technicians. And one of the solutions below is bound to fix the problem for you. No worries, we’ve got you covered.

How can I fix it?

Here are 4 solutions for you to try. You may not have to try them all; just work your way down until you find the one works for you.

Method 1:Try another USB port
Method 2:Update all possible device drivers
Method 3: Disable USB selective suspend settings
Method 4: Re-enable USB controller driver

Method 1: Try another USB port

If you are with a desktop, try to connect your USB device to your computer via the USB ports at the back of your computer case. The USB ports at the back usually have stronger electricity power coming through, which will allow a more stable power supply to your USB device.

If you are with a laptop, try unplugging your USB device from its current port and plug it into a different one. Try not to use any USB hubs.

If your problem stops here, the USB port might be at fault, not your USB flash drive. Try to avoid using the same port next time, in case similar problem happens again.

Method 2: Update all possible device drivers

Another possibility for your not-recognized USB device is outdated, missing and/or faulty drivers. You should verify that all your devices have the right drivers, and update those that don’t. This is especially true for your motherboard driver, your USB port drivers, and your external hard drive driver.

Manual drivers update – You can try to update needed device drivers via the Device Manager one by one, or Windows Update if you’re on Windows 10. If Windows Update or Device Manager fails to locate the appropriate drivers for you, you can also go to the manufacturer support website and search for the device drivers by yourself. The process could take quite some time if you’re not particularly familiar with the driver update process.

Automatic drivers update – If you don’t have the time, patience or computer skills to update your drivers manually, you can do it automatically with Driver Easy . Driver Easy will automatically recognize your system and find the correct drivers for it:

1. Download and install Driver Easy.

2. Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3. Click the Update button next to the flagged drivers to automatically download and install the correct versions (you can do this with the FREE version).

Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system. (This requires the Pro version which comes with full support and a 30-day money back guarantee. You’ll be prompted to upgrade when you click Update All.)

4. You need to restart your PC for the updated drivers to work properly. Check if your USB device is recognized now.

Method 3: Disable USB selective suspend settings

Selective suspend is a feature allowing your computer to assign certain USB ports to a power saving mode, just like the sleep mode of your PC. It’s very handy when you are only on battery with your laptop or tablet.

The problem is, for desktop users, it’s not that necessary, since desktops are always plugged into power, and it could be the culprit for your not recognized USB device as well. Here is how you can disable it:

1. On your keyboard, press theWindows logo key andS at the same time, type in the search boxpower plan and clickChoose a power plan .

2. ClickChange plan settings next to the plan option you’re having now.

3. ClickChange advanced power settings .

6. Check to see if your USB device is recognized now. If the problem remains unsolved, proceed with the methods below.

Method 4: Re-enable USB controller driver

Unstable or corrupted USB controller driver could also be the cause of your not recognized USB device. You can easily fix it by re-enabling your USB controller driver. Here is how you can do it:
