Sony Ericsson Device 115 USB WMC Device Management (COM66) Driver

The Sony Ericsson Device 115 USB WMC Device Management (COM66) driver helps Windows recognize and communicate with the device-management interface exposed by a compatible Sony Ericsson phone over USB. It is intended for users whose connected device appears as an unknown device, shows a driver warning, or is not detected correctly by compatible phone-management software.

Key Features

• USB interface recognition: Helps Windows identify the Sony Ericsson device-management interface rather than leaving it listed as an unrecognized USB component.
• Serial communication support: Enables compatible software to access the management interface through a Windows COM port. COM66 is the assigned port in this device name; the number can vary between computers.
• Device-management connectivity: Provides the driver layer needed for supported management tools to communicate with the connected device. Available functions depend on the phone and software used.
• Legacy Windows support: Intended for Windows 10, 8.1, 7, Vista, and XP, subject to the specific driver package’s compatibility and system architecture.

How to Install Sony Ericsson Device 115 USB WMC Device Management (COM66) Driver

1. Check your system. Confirm your Windows edition and whether it uses a 32-bit or 64-bit architecture. For Windows 10/11 systems, check compatibility carefully: Windows 10 is listed as supported, but Windows 11 support is not confirmed.
2. Choose a matching package. Before starting a Sony Ericsson Device 115 USB WMC Device Management (COM66) driver download for Windows, verify the package’s supported systems and device identifiers. If offered as a free download, still check its source and authenticity.
3. Prepare the files. Extract the downloaded archive if necessary. If the package includes a setup program, follow its instructions, including when to connect the phone.
4. Install through Device Manager if needed. Connect the device with a working USB data cable, locate its entry in Device Manager, and select Update driver. Choose the option to browse your computer and point Windows to the extracted driver folder.
5. Verify detection. Restart if prompted, then check that the device appears without a warning icon. Test the connection using compatible Sony Ericsson management software.

Keep the driver updated when a verified, compatible release addresses connection problems or improves support for your system. Choose the latest version that explicitly supports your device and Windows edition—not simply the newest package available. If an update causes problems, use Device Manager’s rollback option when available.
