I did an additional quick test. I had all the USB connections as before but used the local copy of Kstars/Ekos on RPI4.I ofcourse chose the setup option that equipment was directly connected to local machine. On the Windows PC Kstars/Ekos I chose equipment connected to remote device (RPI4). This time the mount connected just fine. This tells me that the driver works just fine. I have invested a lot of setup time and downloads to configure the Windows version of Kstars/Ekos so I am not ready to switch versions of Kstars.
