Sony Ericsson Device 1039 USB WMC Device Management (COM6) Driver

The Sony Ericsson Device 1039 USB WMC Device Management (COM6) driver helps Windows recognize the USB device-management interface on a compatible Sony Ericsson device and communicate with it through a virtual COM port. It is intended for users whose connected device appears as unrecognized hardware or whose compatible management software cannot access the interface. Although sometimes listed under Printer, this entry identifies a device-management connection rather than a conventional printer driver.

Key Features

• USB interface recognition: Helps Windows identify the device-management interface instead of displaying an unknown device when the appropriate driver is missing.
• Virtual serial communication: Enables compatible software to access the interface through an assigned COM port. The port number may differ from COM6 on your computer.
• Device-management support: Provides the connection layer used by compatible Sony Ericsson utilities; the driver itself does not replace those applications.
• Compatibility-based setup: When selecting a package for Windows 11, 10, 8, or 7, check its supported operating systems and architecture. Older drivers may have limitations on Windows 10/11.

How to Install Sony Ericsson Device 1039 USB WMC Device Management (COM6) Driver

1. Confirm the device identity. Open Device Manager, locate the connected device, and check Properties > Details > Hardware Ids. Match these identifiers to the driver package rather than relying only on the displayed name.
2. Choose a compatible package. Before starting a Sony Ericsson Device 1039 USB WMC Device Management (COM6) driver download for Windows, verify the supported Windows version and whether your system requires a 32-bit or 64-bit package. Choose the latest version explicitly compatible with your hardware.
3. Download and extract the files. Use a trusted source for a free download, preferably official vendor support where available. Scan the package with Windows Security and extract compressed files before proceeding.
4. Install the driver. Run the supplied installer, if included. Otherwise, right-click the device in Device Manager, select Update driver > Browse my computer for drivers, and select the extracted folder. Do not force installation if Windows reports a compatibility mismatch.
5. Verify the connection. Restart if prompted, reconnect the device, and check Device Manager for warning icons. Confirm that your management software uses the assigned COM port.

Keep the driver updated when a compatible update addresses connection problems or Windows compatibility. A newer package is not automatically a better match for older hardware, so retain a working driver and use Device Manager’s rollback option if an update causes issues.

Common Issues and Fixes

• Install fails or shows Code 10/28: The older Sony Ericsson INF may be rejected or mismatched. Run the installer as Administrator, use the correct 32/64-bit package, and reinstall via Device Manager > Update driver > Browse after rebooting.
• Device not detected / no COM6: Use a data-capable USB cable and a direct port, not a hub. In Device Manager, check Ports (COM & LPT) and USB controllers for yellow-marked entries; uninstall them, unplug/replug the device, and rescan.
• COM port or version conflict: COM6 may be reserved or an older Sony Ericsson driver may override the current one. In Port Properties > Advanced, assign a free COM port, remove stale Sony Ericsson USB WMC entries, then reinstall only the current driver package.
