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.
