While virtualizing a USB bus was once a common IT workaround for dongle issues, modern licensing methods have made the physical key largely obsolete for legitimate users. If you are struggling with a dongle that won't read or a "Hardware Key Not Found" error, the best path forward is to contact your local Mastercam Reseller. They can help transition you to the modern, dongle-free licensing system, saving you the headache of managing virtual drivers.
In CNC (Computer Numerical Control) manufacturing, Mastercam is an essential CAD/CAM tool for creating high-precision toolpaths to machine complex parts. Like many professional software, Mastercam requires a license verification mechanism. A physical hardware key (USB dongle, HASP, or NetHASP) has historically been the standard method.

The is a critical software component used primarily to emulate physical hardware security dongles (HASP or Sentinel keys) required to run CAD/CAM software. Historically, Mastercam utilized physical USB keys to verify licensing. In modern operating systems like Windows 10 and Windows 11, engineers and technicians often encounter virtual USB bus emulators (such as MultiKey) when dealing with legacy licenses, remote server hosting, or software testing environments. What is a Virtual USB Bus in Mastercam?
If you are attempting to use a "Virtual USB Bus" driver to emulate a hardware key (sometimes called a "multi-key"), you should be aware of the dangers: Are you experiencing a specific or looking for
Alternatively, open Command Prompt as Administrator and execute: bcdedit /set testsigning on Use code with caution. Restart your computer to enter Windows Test Mode. Step 2: Install the Registry Keys
Using a virtual USB bus introduces specific risks to an industrial workstation environment:
: Open Device Manager (Win + X > Device Manager). Expand "System devices" or "Universal Serial Bus controllers" . Find any entry named "Mastercam X7-2022 Virtual USB Bus" , "Virtual Usb Bus Enumerator" , or "Virtual USB Multikey" . Right-click the device and select "Uninstall device" . In the confirmation dialog, ensure you check the box "Delete the driver software for this device" before clicking Uninstall.
The virtual bus integrates with Windows Plug and Play subsystem, appearing as a legitimate system device. This integration is so seamless that Mastercam cannot distinguish between a virtual and physical license key during normal operation.
