19-pin to dual 9-pin adapter

The Vszerda adapter converts a single motherboard USB 3.0 19-pin header into two USB 2.0 9-pin connectors. It is aimed at builders whose chassis provides more front-panel USB 2.0 ports than the board has native 9-pin headers. The FE 1.1S hub chipset handles the signal translation and is compliant with the USB 2.0 specification.

Build integration

The board plugs directly into the 19-pin (20-pin) header and accepts two standard 9-pin (10-pin) cables from the case front panel. No extra power connector is required because the hub draws bus power from the motherboard header. The compact PCB fits in tight corners behind the motherboard tray, freeing the second 19-pin header for other uses.

Upgrade context

This adapter replaces the need to leave front-panel USB 2.0 ports unconnected or to add a separate PCIe USB card. It is the practical choice when the motherboard has only one 19-pin header but the case supplies two 9-pin cables. Builders who need USB 3.0 speeds on the front panel cannot use this device, because the downstream ports operate at USB 2.0 rates only.

Questions about this item

Does the FE 1.1S chipset throttle under sustained 480 MHz high-speed traffic?

The FE 1.1S chipset is described as working well and stable at USB 2.0 high-speed rates.

How warm does the adapter get when both 9-pin ports run all day?

The compact design has no active cooling; heat will depend on case airflow and total bus load.

Must the motherboard already have a 19-pin (20-pin) USB 3.0 header to use this adapter?

Yes, the adapter requires a mainboard or expansion card with a 19-pin socket for the upstream connection.
