hmm well then the last thing to fix is dolphin. Did you use those drivers that are from the link I posted before? and did you notice any difference between using dolphin.exe and dolphinil.exe?
The very last thing i would suggest is to find out what kind of motherboard you have, its model and make and search the company's website and find the drivers for it. Specifically chipset and usb drivers. You might have better luck after updating all that.
Because im going crazy with this im posting screenshots of all relevent settings Just compare every little thing and i bet one of the settings was the problem in dolphin. It sounds like the controller works fine, i think we missed something in dolphin. I highlighted all the important settings in the printscreen I made. Good luck.
