Multipurpose USB Device


The purpose of this document is to provide information on the Multipurpose USB Device (MUD) included in the PC-Doctor Service Center kits.


The Multipurpose USB Device (or MUD for short) is the most important component in the Service Center kit and provides:

  • License allowing Service Center to authenticate.
  • Boot device for DOS, Bootable Diagnostics, and Android Diagnostics.
  • Installer for Service Center for Windows.
  • Storage to save session information, diagnostic results, and reports.
  • Test/Dongle status LEDs 
  • USB port test functionality.

While running Service Center diagnostics, the MUD must remain plugged in to a USB port at all times.

Additional Information

The MUD is protected by a one year limited warranty. If you are experiencing issues with your device please submit a technical support ticket by visiting this link Contact Tech Support

Caution: Electrostatic discharge (ESD) can damage the motherboard, components, and the USB device. Always install components at an ESD-controlled workbench. If such a workbench is not available, wear an antistatic wrist strap when handling the Multipurpose USB Device.
