[amsat-bb] new computer doesn't see Keyspan adapters

I have purchased a new MacBook Pro computer running Mac OS 10.15.6 with USB-C portsIt is just like my old MacBook Pro computer with USB-A ports, running the same OS except while my older computer sees my Keyspan usb to serial adaptors and gives me radio and antenna control, my new computer doesn't see these adaptors for some reason.I have went to Keyspans web page and downloaded a newer driver but still not seeing these adaptors.Does anyone else have this problem or have a solution?I will try calling Keyspan tomorrow.
