USB Connecting and Disconnecting
USB Connecting and Disconnecting

Resolving USB disconnection issues involves several steps, each addressing different potential causes. Combining information from Darwin’s Data and 4DDig Tenorshare, here’s a comprehensive guide to troubleshoot and fix USB disconnections:

  1. Check the USB Cable Connection:
    • Inspect the cable for damage or loose connectors.
    • Try connecting the device to another computer to rule out issues with the cable or device.
    • Ensure the cable is securely connected at both ends.
    • Avoid using hubs or extenders; connect directly to the computer.
    • Consider replacing the USB cable if it’s old or damaged​​.
  2. Update Drivers:
    • Update USB drivers through the Device Manager in Windows.
    • For USB host controllers and chipset/motherboard drivers, visit the manufacturer’s support website to download the latest drivers​​.
  3. Update BIOS:
    • Check for BIOS updates on your computer/motherboard manufacturer’s website.
    • Carefully follow instructions to update BIOS, which can resolve USB connectivity issues, especially in older systems​​.
  4. Switch USB Ports or Use a Powered Hub:
    • Try different USB ports on your computer, alternating between USB 3.0 and USB 2.0 ports.
    • For laptops, switch the side of the USB connection if possible.
    • Using an external powered USB hub can provide stable power delivery, especially for high-power USB devices​​.
  5. Disable Power Saving Modes:
    • Access Power Options in Windows Settings and disable USB selective suspend or power-saving modes to prevent disconnections​​.
  6. Basic Troubleshooting Steps:
    • Restart your computer as a first step.
    • Test the USB device on different ports and computers to identify the issue.
    • Disable fast startup in Windows settings and reboot the computer​​.
  7. Reinstall Universal Serial Bus Controllers Driver:
    • Faulty drivers can cause disconnections. Reinstall USB controllers drivers through Device Manager.
    • After uninstalling the driver, reboot your computer to allow Windows to automatically reinstall the drivers​​.
  8. Configure Power Management Settings:
    • In Device Manager, under the Universal Serial Bus Controllers section, adjust power management settings to prevent the computer from turning off USB devices to save power​​.
  9. Disable the USB Selective Suspend Setting:
    • Through Control Panel, under System and Security > Power Options, disable the USB selective suspend setting​​.
  10. Run Hardware and Devices Troubleshooter:
    • Use the built-in troubleshooter in Windows to identify and fix issues with USB devices​​.
  11. Run the SFC Scan:
    • Use the System File Checker (SFC) scan to check for corrupted system files that might be causing connection issues​​.

By systematically following these steps, most USB disconnection issues can be diagnosed and resolved. If the problem persists after trying these solutions, it may be necessary to seek assistance from a professional technician or the device manufacturer.
