This is a teardown of a dual USB port bracket with LED activity lights for a desktop computer. These brackets, which mount on any open expansion card slot on a computer chassis, add two USB ports to the back of a computer using a connection to a 9-pin USB header on a motherboard. This one came out of a desktop with an MSI motherboard.

Why does it need its owe usb header just for the LED's.
That "usb header" is especially for MSI motherboard diag. status (mobo K8T Neo2 FIR 6802E, D-Bracket 2)
