Hi all,
I just got one of those front panel Multi io things from eBay. It has 6 usb2 and 2 usb3.0 outputs. The usb2 stuff is going well, but the (alleged) USB 3 headers on the motherboard are 9-pin about a cm apart, while the plug is the now-standard 20-pin.
I looked for an adapter with two usb3 nine-pins going into a usb 19/20 pin header. There are a lot of cables that will reduce 20 to 9 for you, but that also reduces the port to usb2 operation, if I understand it aright.
The 19/20 port plug from the new panel looks like it is just two parallel 9pins joined together. There are separate cables to the front panel. I am seriously considering cutting very carefully through the plug to split it into two. Should I? Or are the pinouts assigned all over the place? How can I increase my chances of success?
