Most external hardware connects to a computer system via a universal serial bus data cable. If the connector on the equipment is not functioning correctly, the computer is unable to use or detect the USB device. To fix the USB connection, perform a few different troubleshooting steps, ranging from cleaning off the connection port to changing the USB connector on the computer.
Things You'll Need
- Soft cloth
- Compressed air
Check the USB connection. Ensure the cable inserts completely into the USB port on the computer. If it isn't plugged in all the way, the computer is not going to detect the equipment.
Disconnect the USB device and then plug it back into any other USB port on the computer. On occasion, some USB ports fail to detect some hardware or just die out. Changing out the connection fixes this issue.
Download the latest driver for the device. Open the Internet browser and then navigate to the manufacturer's website for the hardware, select "Support" and choose the equipment connected to your computer. Click the download link to download the driver, then double-click the downloaded driver and follow the prompts to install the driver onto the computer.
Disconnect the cable from the computer, then clean off the USB connector with a soft cloth. If the USB connector is dirty, the computer is not going to read the hardware properly
Spray a few shots of compressed air into the USB connection port to clean out any dirt and dust stuck in the port, preventing the computer from reading the hooked up hardware.
