Computex 2014 ASUS displays USB 3.1 on two prototype motherboards at the show. USB 3.1 doubles USB 3.0 performance, all the way to 10Gb/s. It seems USB-IF doesn't want to get left behind by Thunderbolt and is quickly ramping up performance. For motherboard makers, USB is cheaper to implement than Thunderbolt and has backwards compatibility dating back to the mid 90s and has widespread support from peripherals, storage, monitors and even accompanies CE products.
It truly lives up to it's name as the Universal Serial Bus.
