CH340 Not installing

[Nicokno1]

My problem is that when I install the driver it does not detect the board, so when I uninstall it I get a message as if it had never been installed in the first place, I tried to restart, change the port, download the driver from other sources

It explains that you'll need to to an uninstall too.

[Nicokno1]

You're not uninstalling a device, you are uninstalling a driver
