# HP USB 3.0 SuperSpeed PCI-e x1 driver

HP <span class="caps">USB</span> 3.0 SuperSpeed <span class="caps">PCI</span>-e x1 add-in card commonly found in HP desktops, circa 2010 and 2011 driver.

Common low-profile add-in card found in HP 8200 Elite <span class="caps">CMT</span> (convertible mini-tower), HP 8200 Elite <span class="caps">SFF</span>, HP Z400 workstations, and other HP systems.

Identified as part number *BU994AV* in many price quotes and configurations. Sticker on rear of card may say:  
*CHI314PCB-2 Rev 2.3*  
*PN: 607782-001*  
*<span class="caps">SPN</span>: 608151-001*

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