Try the latest driver. Also try a new USB cable to eliminate a cable issue.
actually we just went and bought a new computer..... the other one would not have run Fusion 360 anyway so might as well bit the bullet.... new omputer loaded up no problem was up and running in no time

I'm not confident what drivers need to be updated. When I connected the other day, the jog controller buttons were grayed out, but no errors. Eventually, I got the Serial/COM port error. I have several versions of it that I am no longer confident in what needs to be done.
