As a group, mice, keyboards, printers, and USB storage devices are called “USB devices.” These devices talk to a computer through its USB ports, making life easier for PC users. However, problems with the devices, such as unknown USB device problems, can happen.
If you don’t know the problem with a USB device, you won’t be able to use its features and functions. These problems could be caused by USB connections that are broken or not tight enough. There are also often problems with device drivers, like lost, damaged, or out-of-date drivers. Here are the most common ways to fix and keep these USB device problems from happening.
Check the USB plugs and cables.
A loose link in the USB port sometimes causes an unknown USB device. To fix this, you can try to reconnect your device. Make sure to plug its USB cord back in tightly and correctly, and then check to see if your computer can already see it.
If the USB port connection is not loose, look closely at the USB cord to see if it is broken or has any other problems. You can also ensure the USB connection works by connecting another device to your computer.
Install the Drivers That Are Needed
When you connect a mouse, keyboard, or USB hub to a computer, Windows OS will instantly install the drivers for those devices. Other USB devices, like printers, scanners, and mobile phones, may need special device drivers to connect to a computer. If you don’t install the drivers for these devices, they will appear in the Device Manager as “unknown devices.”
To fix unknown USB problems caused by missing drivers, you must install the drivers you need from the startup CD. If you don’t have the software CD, you can search for and download the drivers for your device on the company’s website that made it.
Put the Drivers back on.
“USB Device not Recognized” is an error message that means the USB device you plugged into your computer is unrecognized. Most of the time, this problem happens because your computer can’t find the needed device driver or the driver is broken or corrupted. You can restart your computer and let it see the driver for your USB device again. If that doesn’t work, you can try the steps below:
Open the Device Manager.
Right-click on the “Unknown USB Device”
Properties will open.
Choose the Driver tab.
Click Remove.
Click the OK button.
Restart your PC.
Check to see if the Device is already found.
If the above solution doesn’t work, try using the installation CD to manually reinstall the device driver for the USB device (the same way you did when you first installed the device).
Use an Update Tool You Can Trust
You can also use a trustworthy driver update tool that can immediately fix device driver problems. This choice will not only help you get the latest drivers by downloading them automatically, but it will also walk you through the installation process. If you choose this choice, you won’t have to spend time and energy looking for device drivers or updates online, and you won’t have to worry about installing the wrong or incompatible device drivers, which can be dangerous.
To sum up, if a USB device stops working suddenly, you must ensure that the USB connector is firmly plugged into the USB port and that the USB cord is not broken. If missing drivers cause the problem, you must load the drivers the hardware needs. If a damaged or faulty device driver causes pain, you can update the driver using the Device Manager or download a new version from the Internet. Last but not least, you can also use a reliable driver update tool that can immediately fix unknown USB device problems caused by device driver problems.
