Go into device manager and look at your Universal Controller Bus (USB). Make sure you don't have any that has a Question Mark or Exclamation Point on them. It looks like somewhere you don't have the correct drivers. Are you sure your USB Ports are 2.0?

I would suspect it is a wheel bearing issue, if it sounds similar to a baseball card in the spokes of a bicycle, stays somewhat same pitch just louder with speed that is where I would look. Does noise go away or change when making turns?

Don't know what the "whirring" is, but you NEED to find it. The only reason your temp. goes down at higher speed, is cuz more air is rushing past your car, cooling the engine and radiator. Careful you don't burn up the engine! Find the cause of the overheating, probably related to the sound you hear, or caused by overheating, even maybe causing the overheating. Take your time and work on it or have it serviced. Start by checking your coolant level. Good luck.

change electronic module on side of transmission

no any problem and don't worry the fan changing speed is normal it's a property

LE error? Don't buy a new sensor, don't call a repairman and don't scrap it. The fix is EASY!

Turn the drum 4-5 times by hand to resettle the load, move spin speed to highest, Quick Wash, Speed Wash. It shoudl work just fine. I've had to do this a few times over the last 5 years. Why everyone wants you to BUY parts is beyond me....maybe they need to make some $$ ?
