Printing to my Gmax via USB Linux

#1
Anyone know where to start to make this work I have both Cura and Simplify 3D working just not sure what kernel driver I need for USB 3D pprinting or if I need additional software. Any suggestions would be greatly appreciated. I am running CRUX Linux by the way which is source based.

I have this Issue too.
gMax 1.5+ Windows 10, Cura 3.1
I have a long USB-AB cable that, when plugged into the gMax, powers up the LCD screen and controller.
It does not connect to my computer, devices will not pick it up, Cura won't, Windows 3D Print won't.
I need advice.
