I would suggest checking directly with the OEM to see if you can disable USB 3.0 from BIOS or if they can provide some alternative.
Thanks. But I already mention in my message that I would not like to have to deal with it at the Bios level. This can be done in software, from within Windows, as I have already tested (and am able to duplicate at will). I am just asking to see if there is a more elegant way to do it, or even if the folks from Intel read this, maybe they decide to provide a function in the software to do it, this is happening to a lot of people.
