I invested in an Icy Box IB-AC6110 powered 10 port usb hub a while ago too, but it is more for additional controllers, specifically joysticks and the likes. Mainboards just don't have enough USB ports for all that. Dual sticks or a hotas? Two gone. Maybe some pedals? Now it is 3. How about a camera and a head tracker? Well, 4-5 depending on your product solution. Defo gives me some peace of mind to be good on USB ports.
