MTNSP355AWG HS-USB Diagnostics A093 (COM25) Driver

The MTNSP355AWG HS-USB Diagnostics A093 (COM25) driver helps Windows recognize and communicate with the device’s USB diagnostic interface, listed under Qualcomm Atheros. It is intended for users who see this interface in Device Manager and need a compatible driver for diagnostic software or to resolve a missing-driver warning.

Key Features

• USB diagnostic interface recognition: Allows Windows to identify the diagnostic connection rather than leave it listed as an unknown device.
• COM-port communication: Enables compatible service and diagnostic applications to access the interface through an assigned serial port. Although this device name includes COM25, Windows may assign a different port on another computer.
• Legacy Windows compatibility: Listed operating systems include Windows 10, Windows 8.1, Windows 7, Windows Vista, and Windows XP. Select a package that matches your Windows version and system architecture.
• Driver troubleshooting support: Installing the correct package may resolve recognition problems caused by a missing, incompatible, or damaged driver. It does not replace diagnostic software or repair hardware faults.

How to Install MTNSP355AWG HS-USB Diagnostics A093 (COM25) Driver

1. Check your system and device details. Confirm your Windows version and whether it is 32-bit or 64-bit. In Device Manager, open the device’s Properties and check Hardware Ids under the Details tab to verify the package matches.
2. Choose a compatible package. Before starting your MTNSP355AWG HS-USB Diagnostics A093 (COM25) driver download for Windows, review the supported systems and package source. For Windows 10/11 searches, note that Windows 10 is listed here, but Windows 11 support is not confirmed.
3. Download and extract the files. If a free download is available, use a trusted source and scan the archive before opening it. Choose the latest version that explicitly supports your hardware and operating system.
4. Install the driver. Run the included installer if provided. Otherwise, right-click the device in Device Manager, select Update driver, and browse to the extracted driver folder. Follow the prompts without bypassing security warnings.
5. Verify the connection. Restart if requested, then check that the diagnostic interface appears without a warning icon. Configure your diagnostic application to use the COM port currently shown in Device Manager.

Keep a working driver unless an update addresses a relevant issue or compatibility requirement. Before replacing it, retain the previous installer or create a restore point so you can recover if the newer package causes problems.
