Sierra Wireless Gobi 2000 HS-USB Diagnostics 9001 (COM3) Driver

The Sierra Wireless Gobi 2000 HS-USB Diagnostics 9001 (COM3) driver lets Windows recognize the diagnostic USB interface on compatible Gobi 2000 mobile broadband hardware. Listed under Qualcomm Atheros in the USB category, this driver is intended for users whose diagnostic port is missing, appears as an unknown device, or needs to be restored after reinstalling Windows.

Key Features

• Diagnostic interface support: Allows compatible service and diagnostic software to communicate with the module through its USB diagnostic port.
• COM port recognition: Helps Windows identify the diagnostic interface as a serial port. Although the device name includes COM3, Windows may assign a different port number.
• Legacy Windows compatibility: Supports Windows 10, 8.1, 7, Vista, and XP when you select a package appropriate for your computer and system architecture.
• Targeted troubleshooting: May resolve recognition problems caused by a missing or incompatible diagnostic driver. This component alone does not provide a complete mobile broadband connection setup.

How to Install Sierra Wireless Gobi 2000 HS-USB Diagnostics 9001 (COM3) Driver

1. Check your hardware and Windows edition. Open Device Manager and locate the diagnostic interface, which may appear under Ports (COM & LPT) or Other devices. Confirm its hardware IDs and whether your operating system is 32-bit or 64-bit.
2. Select a compatible package. Before choosing a Sierra Wireless Gobi 2000 HS-USB Diagnostics 9001 (COM3) driver download for Windows, compare the supported hardware and operating systems. Choose the latest version compatible with your laptop or module, preferably from its manufacturer.
3. Download and extract the files. For any free download, verify the source and check the package’s digital signature where available. Extract compressed files before installation.
4. Install the driver. Run the supplied installer, or right-click the device in Device Manager, select Update driver, and browse to the extracted driver folder. Follow the prompts without bypassing Windows security warnings.
5. Restart and verify detection. Restart if prompted, then check that the diagnostic interface appears without a warning icon. Use the COM port assigned by Windows in your diagnostic software.

Keep the driver updated when a compatible release addresses a problem or improves support for your system. For Windows 10/11 users, note that Windows 10 is listed as supported, but Windows 11 compatibility is not confirmed here. Check manufacturer guidance before an update, and retain a working driver package in case you need to roll back.
