I have just bought a Plugable USB 2.0 adapter to use with Dolphin as that was one of the best on the compatibility list. So when I recieve it I plug it straight in and install the driver to WinUSB straight away and then try it with Dolphin and after many tries I could not get it to work. Then I realized for the adapter I had I had to force Dolphin to use the adapter so I find the VID and PID which i think is correct and put them in the dolphin.ini notepad config. But even after that i still have no success with it. It just doesnt work. I hope that I didn't spend 12 pound for absoluteley nothing. 
I Hope someone can help me.
