SAMSUNG Mobile USB OBEX Serial Port (COM19) Driver

The SAMSUNG Mobile USB OBEX Serial Port (COM19) driver helps Windows recognize the serial interface used by compatible Samsung mobile devices for OBEX-based communication over USB. You may need it if your connected phone appears as an unknown device, shows a warning in Device Manager, or cannot communicate with compatible file-transfer or synchronization software.

Key Features

• USB interface recognition: Enables Windows to identify the Samsung Mobile USB OBEX serial port when a compatible device is connected.
• OBEX communication support: Provides the driver interface needed by compatible applications for object-exchange functions, such as transferring supported files or contact data.
• Serial port access: Makes the interface available through a Windows COM port. COM19 is the port assignment shown on this system; Windows may assign a different number after reconnection or installation.
• Support for older Windows environments: Intended for Windows 10, 8.1, 7, Vista, and XP, provided the selected driver package matches your device, operating system, and system architecture.

How to Install SAMSUNG Mobile USB OBEX Serial Port (COM19) 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 device’s hardware IDs if you need to verify that a package matches.
2. Choose a compatible package. Before starting your SAMSUNG Mobile USB OBEX Serial Port (COM19) driver download for Windows, review the supported models and operating systems. Select the latest version compatible with your hardware, rather than assuming the newest package supports every Samsung device.
3. Download and prepare the files. Use a trusted source for a free download, extract the archive if necessary, and check the publisher or digital signature where available. Disconnect the phone if the installer instructs you to.
4. Install the driver. Run the included setup program and follow its prompts. If the package contains only driver files, open Device Manager, right-click the relevant device, select “Update driver,” and browse to the extracted folder.
5. Reconnect and verify. Restart Windows if requested, reconnect the device using a data-capable USB cable, and confirm that the interface appears without a warning icon. Test communication with compatible software.

Keep the driver updated when a compatible update addresses connection problems or improves reliability. For Windows 10/11 systems, check support carefully: Windows 10 is listed here, but Windows 11 compatibility is not confirmed. Avoid replacing a working driver with an unverified package.
