USB controller error (Code 43 / 10)

What is USB-CONTROLLER-ERROR?

The motherboard's USB controller reports a Code 43 (device stopped) or Code 10 (cannot start) error in Device Manager. This affects all USB ports managed by the failing controller. Symptoms include USB devices suddenly disconnecting, USB ports not powering devices, or the controller disappearing from Device Manager entirely.

Common Causes

• USB controller driver corruption
• Electrical damage to USB port
• BIOS USB configuration error

Step-by-Step Fix Guide

• 1
  Update or reinstall USB controller drivers

  Reinstalling USB controller drivers through Device Manager resolves most software-caused USB controller failures.

• 2
  Check Device Manager for controller errors

  Physical damage to USB ports (bent pins, water damage) requires motherboard repair or replacement.

• 3
  Reset USB settings in BIOS
