Installing the CH340 driver is essential if your device relies on this USB-to-serial chip. Once properly set up, your Arduino boards and other hardware should connect seamlessly with your computer.

Hi, i'm using arduino ide to program an STM32F103C8T6. I have been spent a lot of time in trying to install the usb driver on my pc rugging W11 (21H2 build 22000.978) using the batch file in "win" ...

I have problem connecting Arduino Uno R4 Minima to Windows 7 host (IDE 1.8.10 and 1.8.19) - after connecting USB, CDC port driver fails to install ("failure of driver installation" window appears).

It's of course backwards compatible with existing Arduino add-ons, but sets itself apart with a new USB controller with lower latency and driver-free operation on Mac and Linux.
