LaserWeb4 not recognizing USB

I’m VERY new to laser engraving. Chinese 40K machine that I have been using with K40 Whisperer but wanted to try different software. LaserWeb4 is not recognizing the USB port. Could the K40 Whisperer driver be a problem? Unsure what else might be causing this. Any help would be appreciated.

Your stock K40 has a built-in controller board which is not supported by LaserWeb. It’s called the M2Nano and so far only K40 Whisperer, Meerk40t and VisiCut support that controller board.

If you go to the Laserweb webpage under documents you will see what controller firmware is supported. Compatibility - LaserWeb / CNCWeb

Thank you so much for the information. Much appreciated.
