I mean, really, how hard can it be? And if they don't want to do it just open up the spec. But no, you have to use their crap software on a platform that I'm not using. Oh, and wait until you look at what the nifty USB connector really is. It just looks like USB, it uses a USB connector but there is a whole raft of secondary connections in there! You'd never know until you look at the plug with a microscope, it's that small.
Yes, it's the "multiport" connector; both USB micro-B and wired shutter release socket.
Never quite understood why (considering the A7II, for example, is an Android device!!) they didn't make that port a USB-OTG setup and make the shutter release a proper USB peripheral. But they didn't.
