I am pleased to report that simply moving the file USB-Mach3.dll into my C:\Mach3\Plugins folder got me connected to my machine immediately upon restarting Mach3. Although the axes aren't fully mapped (I can only move in the Y+ direction at the moment) the machine is clearly communicating with Mach3 and is also aware of when the E-Stop is pushed.
