well, i guess i am into this elbow deep now like it or not. it appears that my usb hub is scrap. my first clue was i tried to insert a flash drive to it, and nothing happened. which now that i think of it, i moved every time i removed and installed the computer into it;s "cubby. anyway, that is when i found none of the 3.0 ports worked. i shut down the computer, removed the usb cable from the back of the computer, and now i have 3.0 ports that function again. i did try another cable, and it still does not work. could the hub cause my intermittent start problem? /// so, i have my best multi meter sitting here, do i need to check every harness for power? or just the 20+4 connector?
