Hereís what Iíve done to try and rectify: The USBís (2 of them on and all-in-one motherboard) show up in device manager, they are indicated as working. I have uninstalled and re-booted, I have searched for updated drivers, (drivers are up to date) I have gone into the BIOS and they are there and configured. Iíve searched forums and where I have found a similar problem, there has never been a solution other than what I have already tried. I did see a suggestion about clearing NVRAM but found no feedback indicating this would help or what it involved.
Appreciate any suggestions.
