You said that you've altered the USB power options in the hardware profiles - do you mean you've done the following?
In Device Manager, expand Universal Serial Bus Controllers, right-click each USB Root Hub(s) [I've got 3!] & select Properties. Go to the Power Management tab & untick 'Allow the computer to turn of this device to save power', & press OK. Note that you may have to do this for EACH USB Root Hub listed. Reboot, even if it doesn't ask you to, then check to see if the problem still occurs. G
