You can use Windows 7, Windows 8.x, Windows 10, Linux Mint, and OSX Yosemite, El Capitan, and Sierra. These operating systems have the CDC drivers pre-installed, which means you shouldn’t need to install any extra software. However, there are a wide range of operating systems out there, so, if you run into driver problems, you can get drivers here.
The CH340G is made by WCH. You can find the latest version of their drivers here, but most of their pages are in Mandarin.
