Internal USB header adapter cable for converting a motherboard USB 3.0 19‑pin header to a USB 2.0 9‑pin connection, ideal for connecting front‑panel USB ports, card readers and other internal USB devices when only legacy headers are available.
Item Description
This USB 3.0 19 Pin to USB 2.0 9 Pin cable adapter is designed to bridge the gap between newer motherboards and older internal USB devices.

Suitable for home users, enthusiasts, IT workshops and refurbishers who need a reliable, low‑cost connectivity solution.
