StarTech USB Card, 2 Sub Ports, USB 3.2 Gen 2 USB Specification - PEXUSB312C3

This USB card provides high-speed USB connectivity by fitting into a PCI Express slot to add two external Type-C ports. It enables modern peripherals to communicate with host systems using the USB 3.2 Gen 2 protocol and is intended for integration into industrial and laboratory workstations that require upgraded transfer interfaces.

Features and Benefits:

• USB 3.2 Gen2 throughput for Faster data transfers
• Two Type-C ports to connect multiple devices
• PCIe Interface for direct motherboard expansion
• UASP support to reduce storage transfer overhead
• xHCI compliance for standardised host controller operation

Applications

• Suitable for data-logging systems requiring high-bandwidth peripheral links
• Ideal for test rigs that need additional USB-C connectivity
• Used for workshop PCs interfacing with modern instrumentation
• Can be used for workstation upgrades in automation control rooms

Which bus does it use to Interface with a host system?

It connects via a PCI Express bus and conforms to the PCI Express Base Specification Rev.3.0 for slot compatibility and signalling.

What protocol improvements help when transferring to external storage?

It supports UASP (USB Attached SCSI Protocol) Rev.1.0 to lower CPU utilisation and improve throughput for storage-class devices.

What USB standards does it implement for device compatibility?

The card implements USB 3.2 Specification Rev.2.0 along with USB Specification Rev.2.0 for broader device interoperability and defined electrical behaviour.

How does the host controller support affect driver interaction?

The device adheres to the Intel xHCI Specification Rev.1.1, enabling standard xHCI driver stacks to manage connected USB devices.
