Sony Ericsson Device 1039 USB WMC OBEX Interface (COM5) Driver

The Sony Ericsson Device 1039 USB WMC OBEX Interface (COM5) driver helps Windows recognize the OBEX communication interface exposed by a compatible Sony Ericsson device connected through USB. It is intended for users who need object-exchange functions, such as file transfers through compatible phone-management software, or who see an unrecognized interface in Device Manager.

Key Features

• USB interface recognition: Enables Windows to identify the device’s USB WMC OBEX interface rather than leave it listed as unknown hardware.
• OBEX communication support: Provides the driver layer used by compatible software to exchange supported objects, such as files, with the connected device.
• COM-port identification: Supports the interface shown here as COM5. Windows may assign a different COM number depending on your computer’s configuration.
• Legacy Windows options: Look for a package matching Windows 10, 8.1, 7, Vista, or XP, and confirm that it supports your system’s 32-bit or 64-bit architecture.

How to Install Sony Ericsson Device 1039 USB WMC OBEX Interface (COM5) Driver

1. Check your Windows version. Open your system information and note the operating system and architecture. For Windows 10/11 systems, verify compatibility carefully: Windows 10 is listed for this device, but Windows 11 support is not confirmed.
2. Choose a matching package. Before starting your Sony Ericsson Device 1039 USB WMC OBEX Interface (COM5) driver download for Windows, compare the package’s supported hardware and OS requirements with your device. Use a trusted source when selecting a free download.
3. Prepare the files. Extract the downloaded archive if needed. If an installer is included, follow its instructions, including when to connect or disconnect the Sony Ericsson device.
4. Install manually if necessary. Open Device Manager, locate the unrecognized device or existing OBEX interface, select Update driver, and browse to the extracted driver folder. Avoid forcing an incompatible driver or bypassing security warnings.
5. Verify the connection. Restart Windows if prompted, reconnect the device using a data-capable USB cable, and check for warning icons in Device Manager. Test communication with compatible Sony Ericsson software.

Keep a copy of the working driver before you update. Choose the latest version that explicitly supports your hardware and Windows edition—not simply the newest package available. If communication already works reliably, review the update notes before replacing the installed driver.
