Controller works in 3.5 but not 4.0??

Quote:How can it be a driver issue if it works on the same computer with Dolphin 3.5? Windows detects the adapter fine.

That is the very nature of how drivers suck. Very often times software changes ( for better or worse ) and expects the drive to do what it right. Just because the older drivers worked does not mean its correct. When you have issues like this its bets not to assume anything and try many things. Updated a drive is always a good idea. Arguing all and any advice you are given is not.
