    CNX-P5V neccessary ?

    I have purchased a CNX-P2140 and the powered USB hub CNX-P5USB.

    The P2140 will supply 12V to my D946GSEJT motherboard and 12V to my Lilliput 669GL touchscreen. Is the additional CNX-P5v required to supply power to the USB hub or do I get the power directly from the car electrical system (R,B,Y and blue does nothing) ?

    USB into computer will be from touchscreen, dongle for wireless keyboard/mouse, and USB to CNX-P5USB.
    USB to hub will be bluetooth dongle (for OBDII and phone), GPS receiver, HD camera via USB (maybe 2).

    Yes you get power for the hub via the car 12v system. It only actually works once it sense's a signal from computer. wire up like you did your P2140 power/gnd/acc. SNO
