Method 4: Reset the USB Driver Stack (For Code 10 Errors)

Sometimes the issue is not wpdmtphw.inf itself but a driver conflict in the USB stack. microsoft driver wpdmtphw.inf

  1. Open Device Manager.
  2. Expand Universal Serial Bus controllers.
  3. Uninstall all entries named:
    • USB Root Hub
    • Generic USB Hub
    • Host Controller (Do not uninstall your keyboard/mouse if they are USB – have a PS/2 backup or restart planned.)
  4. Restart your PC. Windows will reinstall USB drivers, and the MTP stack (including wpdmtphw.inf) will reload correctly.

When to be cautious
