So I got an #RTSystems USB-63 cable from #DXEngineering and I've just run "./usbPortCheckerThingy.sh" in one shell window before plugging it in, and again in an adjacent shell window after, so I could see what to change in the #CQRLOG settings for #rigctl.

THE HOPE is that rigctl will use one cable, flrig will use the other, and they will peacefully coexist.
