If you’re on Windows 10, and you’re seeing this error saying that USB device not recognized after you plug in a device, you’re not alone. Many Windows users say that they have seen this notification pop up.
Annoying as it seems, it’s possible to fix. Here are some of the most effective solutions for you to try. You may not need to try every one of them. Just work from the top down until you find the one works for you.
Sometimes, a simple reboot fix unrecognized USB device. Plug your USB device out, wait for a few minutes, then restart your computer. Plug your USB device back in again.
Try a Different Computer
Try plug your USB device into a different computer. If it doesn’t work on the second PC, your device could be at fault. You may want to get it repaired or buy a new one.
Plug Out Other USB Devices
Too many USB devices on the same machine might create a conflict, which could stop the running of some devices.
To avoid possible conflict among the devices, it is suggested that you disconnect other USB devices and see if the device that you intend to use works.

One of the most common ways of solving this problem is to check if you need a new driver for your device.
You could try to use Windows Update to find the latest driver, but it should be pointed out that this is not always helpful since Microsoft may not provide you with every driver that you need.
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. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.
You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):
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 any flagged drivers to automatically download and install the correct version of that driver (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Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).
