Connect two pins using a USB 3.0 port on the MoBo device.
When you plug a USB 2.0 device into a USB 3.0 port, the D- and D+ wires are used for data transfer. For a USB 3.0 device, it operates with SS_TX and SS_RX connections. I’m not sure if D- and D+ can work together with the standard pairs, but I think they might be compatible. Each 20-pin header contains wires for two ports, with vertical rows holding the pins for one port. If your case has four ports but only uses one 20-pin header on the motherboard, a hidden USB hub chip is likely present, connecting the header to multiple ports.
