I have a Logitech MOMO Racing Force Feedback Steering wheel and hoocked it for the first tme to my laptop. And I am not getting force feedback. I unplug it and plug it in the lights flicker, but never stay on. I have plug in the power supply but the supply box makes this weird wining noise. Now I am on a college campus and when I plug in a camera battey charger sometimes it wines. BUt I was wondering if dell has weak power to usb ports(also I am running threw a splitter that's pluged in but still no luck but I think te splitter is a piece of junk)
