Plug in a USB device which indicates that power is being delivered from the USB port, e.g. a mobile phone. It doesn't have to show that it is connecting to the laptop ''it only has to show that it is charging.''

Go to ''Start > Control Panel > Device Manager > Universal Serial Bus Controllers >'' click ''+'' to expand the list > scroll to first ''USB Root Hub'' entry > right click on the entry and select ''Properties'' > ''Power Management '' and'' uncheck ''the box (if it is checked) next to ''Allow the computer to turn off this device to save power''. Click ''OK''
Do this for all the USB Root Hub entries.
Restart the laptop and when it has booted to the Windows desktop see if:
a) there is power being supplied from your USB ports by plugging in the phone again,
b) that USB devices are being "recognized" when they are being plugged in.

Go to ''Start > Control Panel > Device Manager > Universal Serial Bus Controllers >'' click ''+'' to expand the list > scroll to first ''USB Root Hub'' entry > right click on the entry and select ''Uninstall''.
