Sony HS-USB Android Diag-1 (COM111) Driver

The Sony HS-USB Android Diag-1 (COM111) driver helps Windows recognize a Sony Android device’s USB diagnostic interface and make it available to compatible service tools through a COM port. It is intended for technicians and experienced users who need diagnostic connectivity, particularly when Device Manager shows an unidentified interface or a driver warning.

Key Features

• Diagnostic USB connectivity: Allows compatible software to communicate with the device’s diagnostic interface; it is not a general-purpose file-transfer driver.
• COM-port recognition: Supports detection of the interface shown as COM111. Windows may assign a different port number after reconnection or installation on another computer.
• Windows compatibility: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Select a package that matches both your Windows version and its 32-bit or 64-bit architecture.
• Hardware identification: The device is listed under the USB category with Qualcomm Atheros as the vendor. Verify its hardware IDs against the package details before installation.

How to Install Sony HS-USB Android Diag-1 (COM111) Driver

1. Check the device details. Connect the device using a reliable USB data cable, open Device Manager, and locate the diagnostic interface. Under Properties > Details, select Hardware Ids to help confirm the correct driver.
2. Choose a compatible package. Before starting your Sony HS-USB Android Diag-1 (COM111) driver download for Windows, check the supported hardware, operating system, architecture, and publisher. If offered as a free download, confirm that the package comes from a trusted source.
3. Prepare the files. Extract the downloaded archive if necessary. Use the supplied installer when available, and avoid packages that require disabling Windows security protections.
4. Install the driver. Follow the installer’s instructions, or right-click the interface in Device Manager, choose Update driver, and browse to the extracted driver folder. On older Windows versions, the menu wording may differ.
5. Verify the connection. Restart if prompted, then check Device Manager for a recognized interface without warning icons. Select the assigned COM port in your compatible diagnostic software. Diagnostic access may require a device-specific mode; follow the device’s service documentation.

Keep the driver updated when a verified release addresses compatibility or connection issues. Choose the latest version that explicitly supports your hardware rather than assuming newer is always better. For Windows 10/11 systems, note that Windows 10 is listed as supported here, but Windows 11 compatibility is not confirmed; verify support before you install an update.
