what if i have 2 devices and one hub? the hub has 4 devices on it: touchscreen, OBD-II cable, RF keyboard, and DVD player. The DVD player and the hub have external power being supplied by the second output of the Carnetix 1900....think I'm still good to go?

I am not very familiar with the carnetix, but maybe you can power all the USB stuff off the carnetix.

In any event, the connector is good for, I think I read, 14 amps. You should be fine, as long as your cable is sufficient to handle the amperage. I would not go smaller gauge then 16, perhaps 14 to be ont he safe side, and don't run it too long. EDIT: I MEAND LENGTH WISE, not time wise.
