Silicon Labs VCP Driver

The driver package provides a Virtual COM Port (VCP) interface for Silicon Labs’ CP210x USB‑to‑UART bridge chips, enabling a host computer to communicate with these devices as if they were standard serial ports. It includes both the VCP driver, which presents the bridge as a COM port, and a direct‑access driver for alternative communication methods. The software is available for macOS, as well as Windows, Linux and Android, and supports legacy operating systems through separate downloads.

Target users are engineers and developers who integrate CP210x bridge hardware into their projects and need reliable serial communication from a host system. The driver supplies the necessary kernel‑level support for device enumeration and data transfer, and it is accompanied by application notes and documentation that describe usage and integration details.

What distinguishes this driver is its cross‑platform availability, the inclusion of both VCP and direct‑access options, and the provision of manufacturing and runtime DLLs that must be used with newer driver versions. The package is maintained as a stable release and is supported by Silicon Labs’ knowledge base and community forums.
