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
- 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.
- 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.
- 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.
- 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.
- 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.
