Hi all,
Sorry if this is the wrong place but I have just installed a USB server on a Raspberry Pi 3B called "VirtualHere" Client installed on my Mac.
http://www.virtualhere.com/home
which has enabled me to remote my Minitower Pro over Wifi from my Mac using SkySafari Pro, also works on Windows and Android Clients.
Pretty easy to setup and for one USB connection is free in the trial version which is connected to my iOptron handset .
A cheap alternative to something like Skyfi III.
I have received much information and advice just trying to give back some,
Cliff
