You are definitely correct ! I've read all the guides by Rehabman concerning this solution, and I must admit I feel really intimidated. Even if the guides are very thorough, their depth is kind of blocking me ! I've been wondering for a long time now if the SSDT (regarding these USB problems only) for a specific motherboard would be valid for any copies of the said motherboard ? For example if someone out there puts out a SSDT for a GA-H110N, will everyone having a GA-H110N be able to use this specific SSDT ? Or does it have to be 100% taylor made ?
