I don't want to sound unfriendly, but this seems to be your standard reply to every question in this forum,
and is not very helpful.
As there was no problem with the previous bios versions of the boards this is neither hardware-related,
nor an unfixable problem.
And most certainly it is not a reason for me to buy an other board: as I allready said: just reflashing the previous bios fixed the problem.
each version of the BIOS has it's own issue, that is the reason for the update, they fix one thing then break another, why did they have to mess with the USB code to begin with, no one was complaining about any serious USB issues.
It's almost as if they purposely break something so that someone has job security.
