Sony Ericsson Device 091010 USB OBEX Port (COM28) Driver

The Sony Ericsson Device 091010 USB OBEX Port (COM28) driver helps Windows recognize the USB OBEX interface used by compatible Sony Ericsson devices for object exchange, such as transferring files through supported software. You may need it if your connected device shows an unknown port, fails to communicate with your transfer application, or needs its driver restored after reinstalling Windows.

Key Features

• USB OBEX communication: Enables Windows and compatible Sony Ericsson software to communicate with the device’s object-exchange interface.
• Port recognition: Helps identify the USB OBEX port in Device Manager. Although this device entry specifies COM28, Windows may assign a different COM number on another computer.
• File-transfer support: Provides the connection layer that compatible applications may use to exchange supported files, including photos. Available functions depend on the device and application.
• Legacy Windows support: Intended for Windows 10, 8.1, 7, Vista, and XP, subject to the compatibility information supplied with the specific driver package.

How to Install Sony Ericsson Device 091010 USB OBEX Port (COM28) Driver

1. Check your system and device. Confirm your Windows version and whether it uses a 32-bit or 64-bit architecture. In Device Manager, check the device’s hardware IDs if you need to verify that the package matches.
2. Select a compatible package. Before starting your Sony Ericsson Device 091010 USB OBEX Port (COM28) driver download for Windows, review the supported systems and publisher details. Choose the latest version that explicitly supports your hardware and Windows edition; a free download should still come from a trustworthy source.
3. Prepare the files. Extract the download if it is compressed, and read any included instructions. Connect or disconnect the device as directed by the package documentation.
4. Install the driver. Run the supplied installer, or open Device Manager, right-click the relevant device, select Update driver, and browse to the extracted driver folder.
5. Verify the connection. Restart if prompted, reconnect the device using a data-capable USB cable, and check Device Manager for warning icons. Test communication with your compatible Sony Ericsson application.

Keep the driver updated when a compatible release addresses connection problems or improves stability. For Windows 10/11 systems, check support carefully: Windows 10 is listed here, but Windows 11 compatibility is not confirmed. Avoid forcing an unsupported update, and retain a working driver package in case you need to roll back.

Common Issues and Fixes

• Install fails or driver won’t start: Remove existing Sony Ericsson USB/PC Suite drivers, then reinstall the matching package as administrator. In Device Manager, uninstall the OBEX Port and related Sony Ericsson USB Composite Device, reboot, and let Windows re-detect it. Avoid generic USB serial drivers.
• Device not detected / no COM port: Confirm the phone is in the correct USB mode for OBEX/PC Suite, not mass storage, and try a known-good cable directly to a rear USB port (no hub). Check Device Manager for the port; if missing, scan for hardware changes and manually update the driver.
• COM28 conflict or version mismatch: In Device Manager → Ports → OBEX Port → Properties → Port Settings → Advanced, change COM28 to an unused lower COM number. Uninstall older Sony Ericsson driver versions and keep only one compatible package installed.
