Thanks for spreading the word. USB 3 has been out for a while, but I’ve never read anything about back compat and had to discover it for myself.
I appreciate you bringing up the subject to begin with. It’s very confusing for those buying boards that have both native USB 3.0 and ASMedia USB 3.0 or similar. I would rather boards not have any third party controllers but that isn’t too common except for genuine Intel boards like the DQ77KB. The situation is potentially much more complicated for laptop users though.
