Minor enhacement of site USB Connection Issues

I propose a minor add on on site

https://docs.cubepilot.org/user-guides/autopilot/the-cube-series-firmware-and-connection-troubleshooting#usb-connection-issues

USB Connection Issues

A further point in USB Connection Issues could be added, similar to

“If in device manager the COM port with ProficNC or similar does not appear after connection your cube, then try a different USB cable.”
