Virtual Usb Bus Error Link | Mastercam X72022
It is impossible to provide a detailed look at this error without addressing the risks associated with the environment in which it occurs.
The "Virtual USB Bus Error" in Mastercam (often manifesting as Error Code 39) typically occurs when Windows cannot verify the digital signature of the virtual driver or when security features like Core Isolation block its execution. This issue is common for users transitioning between versions like Mastercam X7 through 2022 on modern operating systems like Windows 10 and 11. Core Fix: Disabling Memory Integrity
The most frequent cause of this error in newer Windows versions is a security feature called Core Isolation. This feature prevents "unauthorized" drivers from interacting with the kernel. Open Windows Security from the Start menu. Navigate to Device Security on the left-hand sidebar. Click on Core isolation details. Switch the Memory integrity toggle to Off. Restart your computer to apply the changes. Advanced Troubleshooting Steps
If disabling Core Isolation does not resolve the issue, consider these alternative solutions:
Registry Edit (Error 39 Fix): Corrupted registry entries can block USB controllers. Open regedit and navigate to:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\36FC9E60-C465-11CF-8056-444553540000Look for UpperFilters in the right pane and delete it. Restart your computer afterward.
Driver Signature Enforcement: Some virtual drivers require you to disable driver signature enforcement permanently or use a "Driver Signature Enforcement Overrider" tool to sign the system file manually.
User Profile Corruption: In some corporate environments, a corrupt Windows user profile can cause Mastercam to hang in the Task Manager without launching. Creating a new local user profile often bypasses this.
Hardware Conflicts: Unplug all non-essential USB devices (like cell phones or external drives) before plugging in your HASP key or starting the software to avoid driver conflicts. Official Diagnostic Tools

Restart your PC. You will see a "Test Mode" watermark in the corner, allowing the virtual bus to load. 2. Registry Clean-up (Error Code 39)
If you see "Driver is corrupted or missing," you may need to clear the "UpperFilters" in the registry. Open regedit (Registry Editor) as Administrator.
Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\36FC9E60-C465-11CF-8056-444553540000. On the right side, find and Delete the UpperFilters entry. Restart the system. 3. Reinstall HASP Drivers
