How to Fix USB Device Not Recognized
When your computer fails to recognize a USB device, it can lead to a variety of problems. Below are detailed troubleshooting and solutions to help you solve the problem of unrecognized USB devices.
1. Check The Physical Connection
First, make sure the physical connection between the USB device and your computer is normal:
Make sure the USB device is firmly inserted into the USB port of your computer. If the connection is loose, the device may not be recognized.
Try plugging the USB device into another USB port on your computer to see if that solves the problem. Sometimes there may be a problem with a particular USB port.
If possible, try replacing the USB cable to rule out the possibility of a damaged cable.
2. Reboot Your Computer And USB Device
Sometimes a simple reboot can solve many temporary problems:
Power off your computer, wait a few seconds, and then restart.
If the USB device has a separate power switch, power off the device and wait a few seconds before turning it back on.
3. Update the driver
Driver problems are one of the common reasons why USB devices are not recognized. To avoid compatibility issues, you can use "Driver Sentry" to automatically detect driver problems and download the latest versions. Here are the steps:
Install and open the Driver Sentry software and click "Scan".
The software will automatically detect outdated or damaged drivers. Click "Repair Now" to update them with one click.
After the update, remember to restart your computer for the new driver to take effect.
4. Check the USB Root Hub
Sometimes, the USB root hub may cause the USB device to be unrecognized. You can try the following:
In Device Manager, expand "Universal Serial Bus Controllers", locate all "USB Root Hub" devices, right-click on each device and select "Disable". Then, right-click on each device and select "Enable". After restarting the computer, check if the USB devices can be recognized normally.
5. Check Power Management Settings
Power management settings may cause the USB device to be unrecognized. You can try the following methods:
In Device Manager, locate the USB Root Hub or related device, right-click on the device and select "Properties". In the "Power Management" tab, uncheck the "Allow the computer to turn off this device to conserve power" option, and then click "OK".
6. Check Device Compatibility
Make sure the USB device is compatible with your computer's operating system and hardware:
Check the device's user manual or the manufacturer's website to ensure that the device is compatible with your operating system and hardware. If the device is not compatible, you may need to replace the device or upgrade the operating system.
7. Use an External USB Hub
If your computer has a limited number of USB ports or is low on power, consider using an external USB hub:
Expanding the USB ports with an external USB hub provides more power support and helps to solve the problem of unrecognized USB devices.
The above is the solution for USB device unrecognized, hope it is helpful to you.
