Disconnect all your USB devices except the keyboard and repower. If it works, then do the same for the mouse. These are basic USB devices and should work.

If you can get into the system (with a minimum of the keyboard working), do a system update -- their may be a fix in 10.7.2, etc.

10.7.0 Originally had issues like reading USB drives, etc. Maybe a 10.7.x update will sort out the usb drivers.

I have been struggling with this problem for weeks! After resetting the PRAM and SMC, etc. I finally went to Apple to get the latest MAC OS update - installed it and restarted and voila!!! My USB port is now working again!!

SOLVED!!!!
