USB Serial Port Driver

The USB Serial Port driver enables Windows to communicate with compatible Microchip USB serial hardware through a virtual COM port. It is useful for users connecting development boards, embedded devices, or other equipment that exchanges data over a serial connection. If your device appears as unrecognized hardware or your serial application cannot find its port, installing the matching driver may resolve the issue.

Key Features

• Virtual COM port access: Allows serial communication software to connect to compatible Microchip hardware over USB.
• Device recognition: Helps Windows identify the USB serial interface and associate it with the appropriate driver.
• Serial application compatibility: Provides a communication path for terminal utilities, configuration tools, and development applications that use COM ports.
• Support for listed Windows systems: Intended for compatible configurations running Windows 10, 8.1, 7, Vista, or XP; check the individual package for operating system and architecture requirements.

How to Install USB Serial Port Driver

1. Identify your hardware and Windows version. In Device Manager, check the device’s properties and hardware IDs. Confirm whether your system requires a 32-bit or 64-bit package.
2. Choose a matching package. Before starting your USB Serial Port driver download for Windows, verify that it supports your specific Microchip-based device and operating system. Select the latest version that explicitly lists compatibility, rather than assuming the newest release supports older Windows editions.
3. Download and extract the files. Use a trusted source for a free download, and extract the archive if necessary. Follow any included instructions about when to connect the device.
4. Install the driver. Run the supplied installer, or open Device Manager, right-click the device, select Update driver, and browse to the extracted driver folder. Administrator permission may be required.
5. Check the connection. Reconnect the hardware if instructed, then look under Ports (COM & LPT) in Device Manager. Note the assigned COM number and select it in your serial application, along with the communication settings required by your equipment.

Keep the driver updated when a compatible release addresses connection problems or supports changes to your system. For Windows 10/11 setups, verify support separately: Windows 10 is listed for this device, while Windows 11 compatibility is not confirmed here. Only install an update that matches your hardware and Windows edition.
