Sony Ericsson Device 091010 USB OBEX Port (COM10) Driver

The Sony Ericsson Device 091010 USB OBEX Port (COM10) driver helps Windows recognize the USB OBEX interface used by compatible Sony Ericsson devices for object exchange, such as transferring photos and other files through supported software. You may need it if your connected device appears as an unknown device, its OBEX port is missing, or your Sony Ericsson transfer application cannot communicate with it.

Key Features

• OBEX communication support: Enables compatible applications to communicate with the device’s USB object-exchange interface.
• File-transfer connectivity: Supports the connection used to exchange photos and other supported files, depending on your device and software.
• Windows device recognition: Helps Windows identify the Sony Ericsson interface and associate it with the appropriate port driver.
• Legacy Windows support: Intended for supported installations of Windows 10, 8.1, 7, Vista, and XP. Check the individual package for operating-system and architecture compatibility.

How to Install Sony Ericsson Device 091010 USB OBEX Port (COM10) Driver

1. Check your system and device. Confirm your Windows version and whether it is 32-bit or 64-bit. In Device Manager, inspect the connected device’s properties and hardware IDs to help verify that the package matches.
2. Choose a compatible package. Before starting your Sony Ericsson Device 091010 USB OBEX Port (COM10) driver download for Windows, review the package’s supported systems and publisher information. If you need a free download, use a trusted source and avoid installers that bundle unrelated software.
3. Prepare the connection. Use a working USB data cable and select the appropriate USB connection mode on your Sony Ericsson device, if prompted. Follow any instructions included with the driver package.
4. Install the driver. Run the supplied installer, or extract the files and open Device Manager. Right-click the relevant device, choose Update driver, and browse to the extracted driver folder.
5. Verify operation. Restart Windows if requested, reconnect the device, and check that its entry has no warning icon. Test communication using compatible software. Windows may assign a COM number other than COM10.

Keep the driver updated when a compatible release addresses connection problems or improves stability. Choose the latest version that explicitly supports your hardware and operating system rather than assuming a newer package is better. For Windows 10/11 users, note that Windows 10 is listed as supported here, but Windows 11 compatibility is not confirmed; verify support before attempting an update.

Common Issues and Fixes

• Install fails or driver is unavailable: Install Sony Ericsson PC Suite/USB drivers first, then reconnect the phone. On newer Windows versions, use a signed driver and run the installer as administrator.
• Device not detected / COM10 missing: Try another USB cable and port, avoid hubs, and confirm the phone is in the correct USB/OBEX mode. Check Device Manager for unknown devices or ports with errors.
• COM port or version conflicts: If COM10 is already used, uninstall old Sony Ericsson drivers and hidden devices in Device Manager, then rescan. If Windows assigns a different COM port, update the application’s port setting or manually change the port in Device Manager.
