Sony Ericsson Device 1039 USB WMC OBEX Interface (COM3) Driver

The Sony Ericsson Device 1039 USB WMC OBEX Interface (COM3) driver helps Windows communicate with the OBEX interface exposed by a compatible Sony Ericsson phone connected over USB. It is needed when the interface appears as an unknown device, shows a driver warning, or is not recognized by compatible phone-management software.

Key Features

• Enables interface recognition: Helps Windows identify the Sony Ericsson USB WMC OBEX interface rather than leaving it listed as an unsupported device.
• Supports OBEX communication: Provides the driver connection used by compatible software for object exchange, such as transferring supported files between a phone and PC.
• Works within a USB connection setup: Supports this specific interface, which may appear alongside other Sony Ericsson USB components in Device Manager.
• Covers legacy Windows environments: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Check the individual package for its supported Windows version and architecture.

How to Install Sony Ericsson Device 1039 USB WMC OBEX Interface (COM3) 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 interface. The COM port number can vary between computers.
2. Choose a compatible package. Before starting a Sony Ericsson Device 1039 USB WMC OBEX Interface (COM3) driver download for Windows, review the package’s compatibility information and source. If offered as a free download, it should not require unrelated software to be installed.
3. Download and extract the files. Save the driver locally and extract it if supplied as an archive. Choose the latest version that explicitly supports your device and operating system.
4. Install the driver. Run the included installer, if provided, and follow its instructions. Otherwise, open Device Manager, right-click the affected interface, select Update driver, and browse to the extracted driver folder.
5. Reconnect and verify. Restart Windows if prompted, reconnect the phone using a working USB data cable, and check that Device Manager no longer reports a driver error. Test communication with compatible phone software.

Keep a working driver unless an update addresses a problem or adds documented compatibility. For Windows 10/11 systems, verify support carefully: Windows 10 is listed for this device, but Windows 11 support is not confirmed. Avoid assuming that a newer package or operating system will work with this legacy interface.
