Hi,
I hope i can help resolve your problem for you.
this may be a problem relating to your system device driver files.
Try This:-
go to My Computer/Control Panel/System/Hardware/Device Manager. at the bottom of the page you will see USB.
If you have any yellow symbols ( exclamation Marks ) then the driver has been corrupted, or installed incorrectly.
if you have a system restore disk. this may solve the problem for you. or recovery cd.
If you require further assistance, please ask.

Mike @ compurepair.

Well let me be the first to say I see you have skills. All of your troubleshooting is exactly by the book. The only thing I see that was not checked is the CMOS (BIOS) setup screen to make sure that the USB function is enabled there. Good luck and let me know how it goes, we have a couple of hundred years of experience at FixYa so keep me updated if you have any more problems.

Thanks. The Fn F7 idea did not work, the Enable/Disable toggle in Control Panel made no difference BUT the simple pressing of the TINY finger pointing next to the power button DID work. Duh!
