Cannot Install CH340 USB Drivers

Hi Guys,

I have successfully built and setup my new CNC machine and have completed the machine setup using WiFi. I find the WiFi not reliable and want to use direct USB connection.

However, no matter what sequence of driver install i use, the comm port driver will not successfully load. i never have problems with other brands of USB to serial devices as we use them all the time.

Screenshots below, any ideas ??

Thanks,

Glen
