Sony Ericsson Device 117 USB WMC Device Management (COM9) Driver

The Sony Ericsson Device 117 USB WMC Device Management (COM9) driver helps Windows recognize the device-management interface exposed by a compatible Sony Ericsson device connected over USB. You may need it if this interface appears as an unknown device, shows a warning in Device Manager, or is unavailable to compatible phone-management software.

Key Features

• USB interface recognition: Enables Windows to identify the Sony Ericsson device-management component rather than leave it listed as an unrecognized USB interface.
• Communication support: Provides the driver interface needed by compatible software to communicate with the connected device for supported management functions.
• COM port identification: Supports the interface shown as COM9 in this device name. Windows may assign a different COM number depending on your system and connection history.
• Legacy Windows support: Intended for Windows 10, 8.1, 7, Vista, and XP, subject to the compatibility of the specific driver package and its 32-bit or 64-bit architecture.

How to Install Sony Ericsson Device 117 USB WMC Device Management (COM9) Driver

1. Check your Windows edition and architecture in System settings. In Device Manager, inspect the device’s hardware IDs to help confirm that the package matches your connected Sony Ericsson hardware.
2. Choose the Sony Ericsson Device 117 USB WMC Device Management (COM9) driver download for Windows that matches your operating system. When selecting a free download, use a trusted source and check the package details before opening it.
3. Extract the downloaded archive if necessary. If the package includes an installer, run it and follow its connection instructions; connect or disconnect the device only as directed.
4. If no installer is provided, open Device Manager, right-click the affected device, and select Update driver. Choose the option to browse your computer, then point Windows to the extracted driver folder.
5. Restart Windows if prompted, reconnect the device with a working USB data cable, and check that its management interface appears without a warning icon. Test recognition in your compatible Sony Ericsson software.

Keep the driver updated when a compatible release addresses a problem you encounter, but verify that the latest version still supports your hardware and Windows edition before you install it. For Windows 10/11 systems, note that Windows 10 is listed as supported here, while Windows 11 compatibility is not confirmed. Avoid forcing an incompatible update, and retain a working driver package in case you need to roll back.
