Stupid Question - USB 2 Ports Into USB 3 Header?

DirkAction · Mar 21, 2012, 07:22 AM

So my old-ish case has 4 USB 2 ports in front. If I connected them to a USB 3 header on my motherboard, would they work? And if so, just at USB 2 speed right? I assume yes and yes, but I've only really worked with USB 2, and all I know is that all the plugs look the same, so I'm not familiar with these.

They should be compatible.

ensure to get the pinout on the USB 2 Connector and the Pinout on the USB 3.0 Header, USB 3.0 has additional Lines in it compared to USB 2.0/1.1/1.0

i'm curious about this, as i have never seen a USB 3.0 header in person to try this.

thats the design of the USB 3.0 header plug that goes into the USB 3.0 Header jack on the motherboard, Most current cases use that connector as some cases had a passthrough cable that hooked up to the back USB 3.0 Connectors on the motherboard

I expected something like this... oh well, guess I'll just use a USB 2 header and hide some excess cable.
