If the issue persists, then the next step is to connect the USB device to a different computer to rule out a more serious hardware issue. When troubleshooting an external hard drive, make sure to swap the USB cable you use to connect the hard drive to your computer for a new one.

How to Fix USB Device Not Recognized

Just like all other hardware devices, your motherboard requires drivers to work correctly. If you haven’t done so in a while, you should check whether you’re using the latest chipset drivers available by going to the official website of the manufacturer of your motherboard. If a newer chipset driver is available, download it to your computer and install it just like any other driver.

We strongly recommend you avoid various third-party driver finders and driver updaters because many of them are scammy and some are even downright dangerous. The only driver update we can recommend is Intel Driver & Support Assistant.

Fix 7: Install the Latest Windows Updates

From time to time, Microsoft releases hotfixes to patch critical issues. For example, KB976972 fixes problems with moving data over USB from a Windows 7-based computer that has an NVIDIA USB EHCI chipset and at least 4 GB of RAM, while KB974476 ensures that USB devices resume from the USB Selective Suspend state correctly. To install the latest Windows updates:

  1. Open the Start menu, type Windows Update, and select the Windows Update option.

Reinstalling your USB controllers can fix unknown USB device errors by replacing an unstable or corrupted controller with a working one.

  1. Open the Start menu, type Device Manager in the Search box, and select Device Manager.
