VKB-SIM

I've read that there's a limit of 4 modules than can be connected together, but what counts as a module?
For instance, if I put together a Gladiator Joystick with a GNX THQ and a THQ grip, that's 4 components - the joystick base, grip, quadrant and throttle grip, could more GNX modules be attached to the setup?

You could have more than 4 modules in the same unit, but not more than 4 of the same kind when it comes to THQ and SEM and not more than 2 FSM-GAs. Also, the German Throttle grip is not considered as an independent module, as it's working only with the THQ.

Ah so I guess you could connect up to 10 modules then? Isn't there current considerations? Should I make sure it's connected to a powered hub or a USB3.0 port above a certain amount of modules?

Powered hub or mainboard USB is always recommended, even if it’s just the joystick.
