Sensitech USB Interface Plus Reader (COM4) Driver

The Sensitech USB Interface Plus Reader (COM4) driver enables Windows to communicate with the reader over USB so compatible Sensitech software can access the connected device. It is intended for users setting up the reader, restoring communication after a Windows reinstall, or troubleshooting an unrecognized USB device or missing COM port.

Key Features

• USB communication support: Provides the connection needed for compatible applications to communicate with the Sensitech USB Interface Plus Reader.
• Serial port access: Allows software that uses a COM port to address the reader. Although this device is listed as COM4, Windows may assign a different port number on your computer.
• Legacy Windows compatibility: Supports Windows 10, 8.1, 7, Vista, and XP when you select the appropriate driver package for your system.
• Device recognition: Helps Windows identify the reader correctly rather than leaving it listed as an unknown device, provided the driver matches the hardware.

How to Install Sensitech USB Interface Plus Reader (COM4) Driver

1. Check your Windows edition and system type, including whether it is 32-bit or 64-bit. For Windows 10/11 systems, note that Windows 10 is listed as supported; Windows 11 compatibility should be confirmed with Sensitech before installation.
2. Before starting your Sensitech USB Interface Plus Reader (COM4) driver download for Windows, verify the package’s source, supported operating systems, and hardware compatibility. If offered as a free download, it should still come from a trustworthy source.
3. Extract the downloaded archive if necessary and read any included instructions. Run the installer and follow its prompts, connecting the reader when instructed.
4. If no installer is included, open Device Manager, locate the reader or unknown USB device, choose Update driver, and browse to the extracted driver folder to install the matching files.
5. Restart Windows if prompted. Check Device Manager for warning icons and confirm the assigned COM port, then select that same port in your compatible Sensitech application.

Keep the driver updated by checking for the latest version compatible with your reader and operating system. An update may resolve documented communication or compatibility issues, but avoid replacing a working driver solely because another package appears newer. Review the release notes and retain a copy of the previous installer when possible.
