Sony Ericsson Device 1018 USB WMC OBEX Interface (COM20) Driver

The Sony Ericsson Device 1018 USB WMC OBEX Interface (COM20) driver helps Windows communicate with the OBEX interface exposed by a compatible Sony Ericsson phone over USB. It is intended for users who need supported phone-management software to exchange files or objects with their device, especially when Windows reports a missing driver or cannot recognize the interface correctly.

Key Features

• USB OBEX communication: Enables compatible applications to access the phone’s Object Exchange interface for supported transfer functions.
• COM-port interface recognition: Helps Windows identify the interface shown as COM20 in Device Manager. The assigned port number may differ between computers or USB connections.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Check the individual driver package for supported Windows editions and 32-bit or 64-bit compatibility.
• Phone-software integration: Provides the device-level connection needed by compatible Sony Ericsson utilities. Although listed under Network, this interface is not a Wi-Fi or Ethernet adapter.

How to Install Sony Ericsson Device 1018 USB WMC OBEX Interface (COM20) Driver

1. Check the device and operating system. Open Device Manager and locate the Sony Ericsson interface or unidentified USB device. Compare its hardware IDs with those supported by the package, and confirm your Windows version and system architecture.
2. Choose a matching package. Before starting a Sony Ericsson Device 1018 USB WMC OBEX Interface (COM20) driver download for Windows, verify its source and compatibility. A free download should still be checked for authenticity; avoid unrelated installers or bundled utilities.
3. Extract and install. If the download includes a setup program, follow its instructions. If it contains driver files only, extract them to a folder you can easily locate.
4. Update through Device Manager if needed. Right-click the interface, select Update driver, and choose the option to browse your computer. Point Windows to the extracted folder and follow the prompts. Do not bypass signature warnings for an unverified package.
5. Reconnect and test. Restart if prompted, reconnect the phone with a data-capable USB cable, and check for warning icons. Test communication using compatible phone-management software.

Keep a working driver unless an update addresses a specific issue or compatibility need. Select the latest version that explicitly supports your hardware and operating system, rather than assuming every newer package will work. For Windows 10/11 systems, note that Windows 10 is listed here, but Windows 11 support is not confirmed.
