Mastercam X7-2022 Virtual Usb Bus Error <UHD 2026>

Technical Report: Mastercam X7-2022 Virtual USB Bus Error Date: [Current Date] Subject: Analysis and Resolution of Virtual USB Bus Errors (Code 10, Code 39, or “Device Cannot Start”) in Mastercam Versions X7 through 2022 Affected Software: Mastercam X7, X9, 2017, 2018, 2019, 2020, 2021, 2022 Affected Licensing Method: NetHASP / HASP USB hardware keys (physical dongles) 1. Executive Summary Users of Mastercam versions X7 through 2022 have reported persistent Virtual USB Bus errors where the HASP key is not recognized, or Windows Device Manager shows an error (commonly Code 10 or Code 39) for a “Virtual USB Bus” device. This error typically occurs after Windows updates, driver conflicts, or improper installation of the HASP/License Manager. The issue prevents Mastercam from launching or operating in licensed mode. This report outlines causes, diagnostic steps, and proven solutions. 2. Problem Description 2.1 Symptoms

Mastercam displays: “No SIM found” or “HASP key not detected” Windows Device Manager shows a yellow exclamation mark under:

Universal Serial Bus controllers &gt; Virtual USB Bus System devices &gt; Aladdin HASP Key or Sentinel HASP

Error codes observed:

Code 10: Device cannot start Code 39: Driver corrupted or missing

Virtual USB Bus device appears even when no physical USB key is plugged in.

2.2 Affected Environments

Windows 10 / 11 (especially after 20H2, 21H2, 22H2 updates) Windows Server 2016 / 2019 (for network licensing) Mastercam License Manager (any version bundled with X7–2022)

3. Root Cause Analysis The “Virtual USB Bus” is not a physical USB port but a software-created bus used by older HASP drivers to emulate USB communication for legacy licensing. The error stems from: | Cause | Explanation | |-------|-------------| | Driver signature enforcement | Windows 10/11 requires digitally signed drivers. Older HASP drivers (pre-2020) are often unsigned or have expired signatures. | | Windows Update conflict | KB5004237, KB5013942, and similar updates change USB stack behavior, breaking virtual bus drivers. | | Corrupted HASP driver installation | Leftover files from previous Mastercam versions cause conflicts. | | Antivirus/security software | Some tools block the installation of virtual bus drivers (e.g., McAfee, CrowdStrike). | | Outdated License Manager | Using CodeMeter or HASP drivers older than version 8.x with Mastercam 2022. | 4. Diagnostic Steps Before applying fixes, perform these checks:

Check Device Manager
