Which motherboard (2017sept) has maximum [number of] usb3.1 gen2 ports?

 

[Suztera]

Currently there is only need for one USB 3.1 gen2 front panel header and one USB 3.1 Gen 2 A and C port on the back I/O.
When adoption for usb 3.1 gen 2 increase, you may see more of these ports added to motherboards but it's down to the motherboard manufacturers.
