The SU-U3V212.V2 is an expansion card that plugs into a PCIe (PCI Express) slot on your motherboard. It typically provides two to four external USB 3.0 ports. Most versions of this card are built around the VIA VL805 or Renesas (NEC) uPD720201 chipset.
Because "SU-U3V212.V2" is often a generic model number used by various manufacturers, the driver you need depends almost entirely on the chipset soldered onto the board. How to Find the Correct Driver
Before downloading anything, you need to identify which controller chip your card uses. You can do this in two ways: 1. The Physical Inspection
Look at the card itself. The largest square chip on the board will usually have text engraved on it.
If it says VIA, you need the VIA VL805 USB 3.0 Host Controller Driver. COM Port Conflict:
If it says Renesas or NEC, you need the Renesas uPD72020x Driver. 2. Device Manager ID If the card is already installed: Right-click the Start button and select Device Manager.
Look for an "Unknown Device" or "Universal Serial Bus (USB) Controller" with a yellow warning triangle. Right-click it > Properties > Details tab. Select Hardware Ids from the dropdown.
Look for the VEN (Vendor) and DEV (Device) codes. You can search these codes online to find the exact manufacturer. Installation Steps
Once you have located the driver file (usually a .zip or .exe), follow these steps:
Disconnect USB Devices: Unplug any devices currently connected to the expansion card to prevent conflicts during the install.
Run as Administrator: Right-click the installer and select "Run as Administrator."
Follow the Setup Wizard: Most VIA or Renesas drivers use a standard InstallShield wizard. Click through and allow the system to register the new hardware.
