Sony Ericsson Device 1018 USB WMC OBEX Interface (COM4) Driver

The Sony Ericsson Device 1018 USB WMC OBEX Interface (COM4) driver helps Windows recognize the OBEX communication interface exposed by a compatible Sony Ericsson phone over USB. It supports object-exchange communication used by compatible phone software for tasks such as transferring files, making it useful when your connected device appears as an unknown interface or cannot communicate with your PC.

Key Features

• USB interface recognition: Helps Windows identify the Sony Ericsson OBEX interface rather than leaving it listed as an unrecognized device.
• OBEX communication support: Enables compatible applications to communicate with the phone’s object-exchange interface; available functions depend on the phone and software.
• COM port integration: Supports the interface shown as COM4 in this device name. Windows may assign a different port number on another computer.
• Legacy Windows support: Intended for Windows 10, 8.1, 7, Vista, and XP, subject to the compatibility of the specific driver package and system architecture.

How to Install Sony Ericsson Device 1018 USB WMC OBEX Interface (COM4) Driver

1. Check your device and Windows edition. Open Device Manager, locate the Sony Ericsson interface, and check its hardware IDs under Properties > Details. Confirm whether your Windows installation is 32-bit or 64-bit.
2. Choose a matching package. Before starting a Sony Ericsson Device 1018 USB WMC OBEX Interface (COM4) driver download for Windows, verify that the package supports your hardware ID and operating system. Choose a trusted source offering a free download, and scan the downloaded files.
3. Install the driver. Extract the archive if necessary. Run the supplied installer, or open Device Manager, right-click the interface, choose Update driver, and browse to the extracted driver folder.
4. Reconnect and verify. Follow any restart instructions, then reconnect the phone using a data-capable USB cable. Check that the interface appears without a warning icon and test it with compatible Sony Ericsson software.
5. Check compatibility if installation fails. For Windows 10/11 systems, do not assume a legacy package supports both versions. Windows 11 is not listed among this device’s supported operating systems; avoid forcing an incompatible driver.

Keep the driver updated when a verified, compatible update addresses connection problems or improves software compatibility. The latest version is only useful if it matches your device and Windows edition, so retain a working driver or create a restore point before making changes.
