Microconnect MC-USB3.0-T4B interface cards/adapter Internal USB 3.2 Gen 1 (3.1 Gen 1)

The Microconnect MC-USB3.0-T4B is an internal interface card that adds USB 3.2 Gen 1 ports to a PCIe-equipped system. Based on a single-chip VL805 controller, it supports USB SuperSpeed (5 Gbps) as well as High-Speed, Full-Speed and Low-Speed devices, allowing connection of mass storage, printers, scanners, hubs, cameras and other USB peripherals. The card is compact and lightweight, designed for simple installation into an available PCI Express slot.

Advantages

This PCIe USB 3.2 Gen 1 card delivers SuperSpeed transfer rates up to 5 Gbps using the VL805 chipset while remaining backward compatible with USB 2.0 and 1.1 devices. Its internal design keeps the solution compact (weight approximately 0.09 kg) and suitable for various desktop and workstation configurations. Installation is straightforward: plug the card into a PCIe slot to expand your system’s USB connectivity.

How to use

Power down the computer and unplug it from the mains. Open the case and locate an available PCI Express x1 (or compatible) slot. Insert the Microconnect MC-USB3.0-T4B card firmly into the slot and secure it with the case bracket screw. Close the case, reconnect power and boot the system. Install any required drivers if the operating system does not automatically recognize the VL805 controller. After installation, connect USB devices to the new ports and verify functionality.

Recommendations

For optimal performance, connect SuperSpeed-capable devices and use high-quality USB 3.0/3.2 cables. Ensure the card is seated in a proper PCIe slot and that system drivers are up to date. If multiple high-bandwidth devices are connected, consider their combined throughput limitations.
