Sony Ericsson Device 120 USB WMC OBEX Interface Driver

The Sony Ericsson Device 120 USB WMC OBEX Interface driver helps Windows recognize the OBEX communication interface on a compatible Sony Ericsson phone connected by USB. It is intended for users who need object-exchange functions, such as transferring supported files through compatible phone-management software, or who see this interface listed as an unrecognized device in Device Manager.

Key Features

• USB interface recognition: Allows Windows to identify the phone’s OBEX interface and associate it with the appropriate driver.
• Object-exchange support: Provides the connection layer used by compatible software for supported file-transfer operations.
• Legacy Windows compatibility: Listed supported systems include Windows 10, 8.1, 7, Vista, and XP. Check the individual package for operating-system and architecture requirements.
• Targeted device support: Addresses this specific Sony Ericsson USB interface. Although listed in the Network category, an OBEX driver alone does not provide Wi-Fi, Ethernet, or USB tethering.

How to Install Sony Ericsson Device 120 USB WMC OBEX Interface Driver

1. Check your system and device. Confirm your Windows version and whether it is 32-bit or 64-bit. In Device Manager, check the interface’s hardware IDs if you need to verify that the package matches your phone.
2. Choose a compatible package. Before starting a Sony Ericsson Device 120 USB WMC OBEX Interface driver download for Windows, review the supported systems and device details. Select the latest version explicitly compatible with your setup; a free download label does not establish compatibility or authenticity.
3. Prepare the files. Download the package from a trusted source, scan it with your security software, and extract it if necessary. Disconnect the phone if the installer instructs you to do so.
4. Install the driver. Run the supplied installer and follow its prompts. If the package contains only driver files, open Device Manager, right-click the relevant interface, select Update driver, and browse to the extracted folder.
5. Reconnect and test. Connect the phone using a data-capable USB cable, restart Windows if prompted, and check for warning icons in Device Manager. Test the connection with compatible Sony Ericsson software.

Keep the driver updated when a verified update addresses a connection problem or supports your configuration. For Windows 10/11 users, note that Windows 10 is listed as supported, but Windows 11 compatibility is not confirmed here. Avoid forcing an unsupported package, and keep a copy of your working driver before making changes.
