Sierra Wireless Gobi 2000 HS-USB Diagnostics 9001 (COM4) Driver

The Sierra Wireless Gobi 2000 HS-USB Diagnostics 9001 (COM4) driver helps Windows recognize the diagnostic USB interface on a Sierra Wireless Gobi 2000 mobile broadband module. It is intended for users troubleshooting an unrecognized device, restoring diagnostic-port access after reinstalling Windows, or setting up compatible service tools—not as a standalone replacement for the module’s mobile broadband drivers.

Key Features

• Diagnostic interface access: Allows compatible diagnostic software to communicate with the module through its USB serial interface.
• Device recognition: Helps Windows identify the HS-USB Diagnostics 9001 interface instead of leaving it listed as an unknown device.
• COM-port support: Provides the diagnostic serial-port connection shown here as COM4. Windows may assign a different COM number on another system.
• Legacy Windows compatibility: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Check the individual package for supported editions and 32-bit or 64-bit architecture.

How to Install Sierra Wireless Gobi 2000 HS-USB Diagnostics 9001 (COM4) Driver

1. Confirm the device. Open Device Manager and locate the diagnostic interface under Ports (COM & LPT), Other devices, or USB devices. Check its hardware IDs in Properties to help verify that the package matches.
2. Choose a compatible package. Before starting your Sierra Wireless Gobi 2000 HS-USB Diagnostics 9001 (COM4) driver download for Windows, verify the operating system, architecture, and laptop or module model. Although the vendor listing is Qualcomm Atheros, prefer a package validated by your computer manufacturer.
3. Download and extract the files. Use a trusted source offering a free download, and select the latest version explicitly compatible with your hardware. Extract the archive if necessary.
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; do not bypass driver-signature warnings.
5. Verify the result. Restart if prompted, then check Device Manager for warning icons and note the assigned COM port. Configure your diagnostic tool to use that port.

Keep the driver updated when a compatible release addresses a problem you encounter. For Windows 10/11 systems, check support carefully: Windows 10 is listed for this device, but Windows 11 compatibility is not confirmed. Avoid forcing an unsupported update, and retain a working driver package in case you need to roll back.
