I'm correcting a few errors in my previous post - sorry 'bout that!:
Thanks for the reply, Larry. In this case I'm not even getting that far. (I've already got NanoVNA-saver working fine and communicating with the NanaVNA on a different machine running Linux Mint 19 32 bit, native. Once I got all the dependencies installed, which I needed to do independently and not from the python setup program, it "just worked," except for the "Save" function for the graphics - but that's another topic.) Rather, my question relates to getting the NanoVNA to work with VirtualBox on a Mac OS X host, and seems independent of the virtual machine OS. The only Wiki that seems relevant to me at this stage of my problem is from Wiki section 3.7.2, RunningNanoVNASharp or TAPR VNAR4 Windows software in Linux virtualbox. This led me to post #4733 here:
/g/nanovna-users/message/4733?p=,,,20,0,0,0::relevance,,virtualbox,20,2,0,33126091, which describes running a Windows virtual machine on a Linux host - not exactly the same as my situation but I'm getting stuck at the 2nd step listed there: "- enable USB on the VM for the STMicroelectronics Virtual COM Port." My Mac OS X host acts like it's using the USB device, and hence I can't connect it to the virtual machine.
