Absolutely yes. Because the Fusion Control Centre software relies on unique instance IDs for each device connected, every Fusion Brain you connect to your computer shows up as a new and unique device. The Fusion Control Centre software has no limitations on the number of devices connected. However USB standards do.

USB standards say that only 255 devices can be connected to a USB chain at any given time. Every hub is counted as a device. So if you had a motherboard with 255 USB ports, you could use 255 Fusion Brains. Every device including keyboards, mice, GPS receivers, WiFi dongles, bluetooth adapters, and lots of others all count as a device.

Also something to consider is the more devices you have connected to single controller, the same maximum speed is being shared over many devices. So with 1 Fusion Brain connected to a USB port and no other USB devices present, it is at its most efficient and fastest sampling rate. With each addtional device attached, the maximum sample speed decreases. To help with this problem we suggest you cluster all your analogue inputs to the least amount of Fusion Brains that you can in a sensory/feedback related setup or cluster all your digital outputs to the least amount of Fusion Brains in complex output related setups. This allows you to throttle the input and output rate for the boards where not all ports are being used saving bandwith for more important sensors. An example would be to place a temperature sensor on a slowly updating Fusion Brain because the temperature now is not very different than the temperature 1 second from now. Then place something like speed or RPM on a higher priority Fusion Brain because 1 second can be an eternity when dealing with such varying measurements and you want to be as accurate as possible.
