When possible, for Microsoft Windows users, we try to have drivers available for download through Windows Update for many of our products. For those products, simply plugging in your device should cause your PC to download and install drivers automatically if your PC has Internet access.
For most of these operating systems two types of driver are available: Virtual COM Port (VCP) drivers and direct (D2XX) drivers. The VCP driver emulates a standard PC serial port such that the USB device may be communicated with as a standard RS232 device. The D2XX driver allows direct access to a USB device via a DLL interface. The best USB to Serial drivers for macOS Drivers for CP2102 / CH340 / CH341 / PL2303 Devices.
