Ingenious part with 2 x USB3.0

Multifunction card reader for the 3.5 "drive bay There are plenty, but few that have two additional USB3.0 ports. This motherboard needed for this a free 19 / 20p. USB3.0 slot. Unfortunately, the card reader only support USB2.0. The price on 9,99 Euro is absolutely top and in which functions simply unbeatable!

Small drawback:
There is no description in so puzzled short one, as the unit must be connected. This includes a reverse polarity protected connectors for USB3.0, and a 4-pin. Pole terminal strip for USB2.0 (not reverse polarity protected!). A quick look into the motherboard manual or on the adjacent, occupied USB slots but usually solves the mystery on which side + and - must be.
