I feel you pain been reading your posts. Just an idea has anyone have you check disabling power management ?

Your computer could be disabling your device on its own to save power.

Get into your device manager, Go under Universal Serial Bus controllers, Right Click (USB Roothub) just the 1st one, click properties, click the Power Management tab, and make sure there isn't a check in > Allow the computer to turn off this device to save power - if there us uncheck and press ok and test ... should work like a charm if its what I think it is.

I cannot devulge how I know this but, I am a pretty smart cookie
