Sony Ericsson Device 091010 USB Serial Port (COM8) Driver

The Sony Ericsson Device 091010 USB Serial Port (COM8) driver enables Windows to communicate with a connected Sony Ericsson device through a USB-based serial interface. You may need it if Device Manager shows an unknown device, reports a missing driver, or your compatible Sony Ericsson software cannot detect the connection. Although listed in the Camera category, this entry identifies a serial communication port rather than a standalone camera driver.

Key Features

• USB serial communication: Provides the interface that compatible software uses to exchange data with the connected Sony Ericsson device.
• Device recognition: Helps Windows identify the USB serial interface and display it under Ports (COM & LPT) in Device Manager.
• COM port access: Allows applications that require a serial connection to select the assigned port. The port number may differ from COM8 on your computer.
• Legacy Windows support: Intended for the listed Windows versions—Windows 10, 8.1, 7, Vista, and XP—subject to the compatibility of the specific driver package.

How to Install Sony Ericsson Device 091010 USB Serial Port (COM8) Driver

1. Check your Windows version and architecture. Confirm whether your system is 32-bit or 64-bit before choosing a package. For Windows 10/11 systems, check compatibility carefully: Windows 10 is listed, but Windows 11 support is not confirmed.
2. Review the download details. Before starting a Sony Ericsson Device 091010 USB Serial Port (COM8) driver download for Windows, verify that the package matches your device and operating system. Choose a trusted source, and check any free download for a valid publisher or digital signature where available.
3. Prepare the driver files. Extract the archive if necessary. If the package includes an installer, run it and follow its connection instructions.
4. Install manually if needed. Connect the device, open Device Manager, right-click the relevant serial-port or unknown-device entry, and select Update driver. Browse to the extracted driver folder and complete the prompts.
5. Verify the connection. Restart if prompted, then check Device Manager for warning icons. Select the assigned COM port in your compatible software if required.

Keep a working copy of your driver before you update it. The latest version is useful when it addresses a connection problem or improves compatibility, but it must still support your device and Windows edition. If a new installation causes trouble, use Device Manager’s Roll Back Driver option when available.

Common Issues and Fixes

• Install fails or rolls back: Run the Sony Ericsson driver installer as administrator and use the package matching your Windows version. Disconnect the phone/USB cable during setup, reboot, then reconnect so Windows can finish installing the USB Serial Port driver.
• Device not detected or COM8 missing: Try another USB cable and port, avoiding hubs. In Device Manager, scan for hardware changes and check Ports (COM & LPT) and Unknown devices. If COM8 is hidden, enable Show hidden devices, uninstall stale entries, then replug.
• Version or COM port conflict: Remove older Sony Ericsson USB serial drivers first, reboot, and reinstall. If COM8 is already in use, open the port’s Properties > Port Settings > Advanced and assign a free COM number; then update the application to use the new port.
