How can I solve the disconnection problem with the USB connection?

Reinstall the USB driver


The problem can sometimes be due to obsolete USB drivers, as mentioned above. Defective drivers can cause the USB stick to be disconnected frequently, so you will need to reinstall the USB drivers. Some users reported that the Microsoft USB 3.0 driver was the cause of the problem. To solve the problem, you must install the USB drivers from the manufacturer of your motherboard. If you do not know the model of your motherboard, you can find it by unscrewing your PC and checking the motherboard manually or with Windows utilities.

Run SFC Scan

The problem of “USB stick always disconnected from the computer” can also occur if some important system files in your Windows are damaged or corrupted. SFC or System File Checker is a utility provided in Windows that helps to repair these damaged and corrupted system files by replacing them with new ones. To scan and repair your system files with SFC scanning, do the following:

  1. Press’Window + Q’ and enter cmd.
  2. Right-click on’Command prompt’ and select’Run as administrator’. A new CMD window appears.
  3. Enter SFC /scannow in the CMD window and press the “Enter” button. The SFC scan begins.
  4. Wait until the SFC scan is complete. When you are finished, reboot your system and connect the USB stick.

Check if it is now accessible via the File Explorer. Copy the data when you can access it, then format the USB stick as a precaution.
