CP210x USB to UART Bridge Controller (COM6) Driver

The CP210x USB to UART Bridge Controller (COM6) driver from Silicon Laboratories lets Windows communicate with compatible USB-to-serial hardware through a virtual COM port. It is needed for applications that exchange serial data with development boards, embedded devices, and other equipment using a CP210x bridge. The COM6 label identifies the port currently assigned by Windows; it is not a separate hardware model.

Key Features

• Virtual serial port access: Allows compatible software to send and receive UART data through a USB connection.
• Hardware recognition: Helps Windows identify the CP210x bridge and make its serial interface available to applications.
• Configurable communication: Supports serial settings such as baud rate, parity, and flow control, subject to the connected hardware’s capabilities.
• Windows driver options: Driver releases are available for Windows 10, 8.1, 7, Vista, and XP, but compatibility depends on the selected package and system architecture.

How to Install CP210x USB to UART Bridge Controller (COM6) Driver

1. Check your system. Confirm your Windows edition and whether it uses a 32-bit or 64-bit architecture. For Windows 10/11 systems, check the package’s compatibility notes rather than assuming a Windows 10 release also supports Windows 11.
2. Choose the correct package. Before starting your CP210x USB to UART Bridge Controller (COM6) driver download for Windows, verify that the release supports your device and operating system. Use a trusted source offering the genuine Silicon Laboratories driver as a free download.
3. Install the driver. Extract the downloaded archive if needed, then run the included installer. If the package has no installer, open Device Manager, locate the device, select Update driver, and browse to the extracted driver folder.
4. Reconnect and verify. Follow any restart prompts, reconnect the USB device, and check Device Manager under Ports (COM & LPT). Confirm that the CP210x controller appears without a warning icon.
5. Select the port in your software. Choose COM6 if that is the assigned port, then match the serial settings required by your equipment. Windows may assign a different COM number after reconnection or configuration changes.

Keep the driver updated when Silicon Laboratories provides a compatible release that addresses your needs. The latest version may not support older Windows editions, so review compatibility before you update and retain a working installer if you need to roll back.
