What is a USB CDC Device Driver?
A USB CDC (Communications Device Class) device driver is software that allows Windows to communicate with USB devices that implement the CDC protocol. The CDC class is a USB device class that allows USB devices to function as communication devices, like virtual serial ports or modems.
USB CDC devices can provide different types of communication interfaces, such as:
The USB CDC driver is specifically designed to enable this communication protocol to work on Windows. When you connect a USB CDC device (like an Arduino board, USB-to-serial adapter, or USB modem) to your computer, the driver allows software on the PC to communicate with the device as if it were a standard serial port.
