Qualcomm HS-USB Diagnostics 9001 (COM52) Driver

The Qualcomm HS-USB Diagnostics 9001 (COM52) driver allows Windows to recognize a Qualcomm-based device’s USB diagnostic interface and make it available to compatible service tools through a COM port. Listed under Qualcomm Atheros in the USB category, this driver is useful for technicians and users who need diagnostic access or are troubleshooting an unrecognized device in Device Manager.

Key Features

• USB diagnostic communication: Provides the connection needed for compatible diagnostic software to communicate with the device’s exposed diagnostic interface.
• COM-port recognition: Helps Windows identify the interface as a serial port. COM52 is the assigned port number on this system; another computer may assign a different number.
• Support for listed Windows releases: Intended for Windows 10, 8.1, 7, Vista, and XP, provided you select a package that matches your operating system and architecture.
• Device identification: Can resolve missing-driver warnings when the package matches the connected device’s hardware IDs. It does not replace the diagnostic software itself.

How to Install Qualcomm HS-USB Diagnostics 9001 (COM52) Driver

1. Check your system and device. 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 compatibility.
2. Choose a matching package. Before starting your Qualcomm HS-USB Diagnostics 9001 (COM52) driver download for Windows, review the supported systems and publisher information. If you need a free download, use a trusted source and avoid installers that bundle unrelated software. For Windows 10/11 systems, note that Windows 11 is not included in this device’s stated support list.
3. Extract and install. Unzip the downloaded package if necessary. Run its supplied installer, or right-click the device in Device Manager, select Update driver, and browse to the extracted driver folder.
4. Reconnect if prompted. Follow the installation instructions, then reconnect the device or restart Windows if requested. Do not bypass driver-signature warnings to force an incompatible package.
5. Verify the connection. Check that the diagnostic interface appears without a warning icon, usually under Ports (COM & LPT). Select the displayed COM port in your compatible diagnostic application.

Keep a working driver unless an update addresses a specific issue or compatibility requirement. The latest version is only appropriate when it supports your hardware and Windows release; check those details before replacing an existing installation.
