Sony Ericsson HS-USB Android Diag sa0102 (COM23) Driver

The Sony Ericsson HS-USB Android Diag sa0102 (COM23) driver helps Windows recognize the USB diagnostic interface exposed by a compatible Sony Ericsson Android device. Listed under Qualcomm Atheros, this USB driver is intended for users who need diagnostic connectivity for supported service tools or want to resolve a missing-driver warning in Device Manager.

Key Features

• USB diagnostic interface recognition: Allows Windows to identify the device’s diagnostic connection rather than leave it listed as an unknown device.
• COM-port connectivity: Provides a serial-style interface that compatible diagnostic software can use. COM23 is the assigned port in this device name; Windows may assign a different number on another computer.
• Legacy Windows support: Listed supported systems include Windows 10, Windows 8.1, Windows 7, Windows Vista, and Windows XP. Choose a package that matches your Windows version and system architecture.
• Targeted driver installation: Addresses the diagnostic interface specifically. It is not a replacement for separate file-transfer, ADB, or other USB drivers your phone may require.

How to Install Sony Ericsson HS-USB Android Diag sa0102 (COM23) Driver

1. Check your system and device. Confirm your Windows version and whether it is 32-bit or 64-bit. In Device Manager, inspect the device’s hardware IDs to help verify that the package matches your diagnostic interface.
2. Choose a compatible package. Before starting a Sony Ericsson HS-USB Android Diag sa0102 (COM23) driver download for Windows, review the supported systems and source. If you use Windows 10/11, note that Windows 11 is not included in the listed support information. Verify compatibility rather than assuming it.
3. Download and prepare the files. Use a trusted free download source and extract the archive if necessary. Check the publisher and digital signature where available; avoid packages that require unrelated software.
4. Install the driver. Run the supplied installer, or open Device Manager, right-click the diagnostic device, select Update driver, and browse to the extracted driver folder.
5. Verify the connection. Reconnect the device and restart Windows if prompted. Check that Device Manager shows the interface without a warning icon, then select its assigned COM port in your compatible diagnostic tool.

Keep the driver updated when a verified release addresses compatibility or connection issues. The latest version is useful only if it supports your hardware and Windows edition, so review compatibility before you update a working installation.
