USB Features	Supports two USB 3.2 Gen 2 ports and two USB 2.0 ports Up to USB 3.2 Gen 2 10Gbps & USB 2.0 (HS/FS/LS) 480Mbps transfer rate Compliant with Universal Serial Bus 3.2 Specification Compliant with Universal Serial Bus Specification Revision 2.0
Number of USB Ports	Two USB 3.2 Gen 2 Cable Ports (Std-A Receptacle) One USB 2.0 2-in-1 Internal 9-pin header The Vbus of each USB Port has a 2.0A Single Channel Current-Limited Power Switch for protection (IC-S0371-08H) 2.0A (72mΩ on-resistance) Single Channel Current-limited Power Switch UL File Number E169910
USB3 cable lock mechanism	Provides the threaded holes for the jack-screws of USB 3.2 A Plug w/Jackscrew lock Cable
USB Bus Power Input	The USB Bus power (5V) are step-down from 12V and the 12V input might from either PCIe Edge Finger or Auxiliary Power Connectors (J1 & J2). Note: If the PCIe Slot can’t supply 12V current high enough then you have to attach the Auxiliary Power from either J1 (ATA 4-pin) or J2 (SATA 15-pin).
