Just got a Mimaki Cg-130FX from an auction. The following solution worked for me with VinylMaster Cut using a standard USB plug.
Install Cutter via Vinyl Spooler, Configure Port Type to "Windows Port" and i used "COM 4"
This is the same settings i use for an older SeikiTech cutter with no issues as well.
Good Luck to anyone who is stumped and is searching for a solution.
