uses exactly the same firmware image as the little usb ones. i also have one of the "full" and "mini" usb ones.

have connected it to the motherboard headers for power, reset, leds etc... including usb directly to motherboard header. documentation is pretty decent, was quite easy.

would still be better if it contained a usb hub on the pcie port, but they've basically just modified their existing design for poe/pcie power in addition to the preexisting usb, and slapped it on a card.
