For some reason this driver is inordinately hard to find on HP’s site and online. HP evidently uses multiple 2-port USB 3.0 PCI-e x1 cards with similar specs. This card uses an NEC chip for two USB 3.0 ports, a SATA connector for additional power from the system power supply (PSU), and a has a PCI-e x1 interface.
