Sony HS-USB Android Serial (COM109) Driver

The Sony HS-USB Android Serial (COM109) driver helps Windows recognize the USB serial interface exposed by a compatible Sony Android device and communicate with it through a COM port. It is intended for users who need that interface for compatible diagnostic or servicing software, or who see an unrecognized serial device in Device Manager.

Key Features

• USB serial communication: Provides access to the device’s serial interface for software that supports it; this is separate from ordinary Android file transfer.
• Device identification: Helps Windows associate the connected interface with the appropriate driver rather than leaving it listed as an unknown device.
• COM port access: Allows compatible applications to select the assigned serial port. COM109 is the Windows port assignment, not a separate hardware model, and may differ between computers.
• Legacy Windows support: Listed for Windows 10, 8.1, 7, Vista, and XP, with Qualcomm Atheros identified as the vendor. Check the individual package for supported Windows editions and system architecture.

How to Install Sony HS-USB Android Serial (COM109) 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 its Hardware IDs to help verify the correct package.
2. Choose a compatible package. Before starting your Sony HS-USB Android Serial (COM109) driver download for Windows, review the compatibility information and source. If a free download is offered, verify its authenticity rather than relying on the download label alone.
3. Prepare the files. Extract the archive if needed. If the package includes a trusted installer, run it and follow its instructions to install the driver.
4. Install manually if necessary. In Device Manager, right-click the relevant device, select Update driver, and browse to the extracted driver folder. Menu wording varies by Windows version. Do not force an incompatible driver or bypass signature warnings.
5. Confirm recognition. Reconnect the device and restart Windows if prompted. Check Device Manager for a serial port entry without a warning icon, then select the assigned COM port in your compatible application.

Keep the driver updated when a verified release addresses a connection issue or adds relevant compatibility. Choose the latest version that explicitly supports your hardware and operating system, not simply the newest package available. For Windows 10/11 systems, note that Windows 10 is listed here, but Windows 11 support is not confirmed; verify compatibility before attempting an update.
