I found a video of what's happening: I am having the same issue with my G27 wheel on GT5/6 on PS3 and Assetto Corsa on PC. It starts up fine and works for a very short time during a race before it completely shuts down. The pedals have severe input lag but usually work and the wheel works fine for about 30 seconds before I feel the force feed back shut down and no inputs work anymore. It will start working again if I unplug and replug the USB for the wheel. Everything works fine in menus with no issues until I start a race then the wheel gives out and everything dies until I unplug the usb but the problem still persists. All inputs work on the Logitech Profiler however I have to hold down the pedals before I see any input. No LED on the shifter and when the wheel cuts out the LEDs freeze in place. Any suggestions on what parts could be failing or solutions?
