My case has two usb ports at front cable being marked roughly the same as above . Cable pins marked power 5v 1 power 5v 2 , data neg 1 data neg 2 . There is only one cable for the two ports so with the pin out above am I supplying one port or are the 3 blocks commoned i.e. pin 1 of usb 1 to pin 1 of usb 2 to pin 1 of usb 3 .
