How many USB headers do I need?

Hi

I am building a PC this second and I was connecting all the connections from the Kolink Aviator case onto my Asrock A320 HDV motherboard but I have one more USB header to connect and I dont see anymore on the motherboard.

I have the usb2 header which is attached to the usb3 connector installed and also a sdcard reader connected into usb.. but I have one more USB connector left to install.

Should I unplug the one that is attached to the usb3 connector and use the other.. or do I need a hub?

I can provide pics if this isnt clearly explained sorry.

Thanks

You don't need to connect both USB2 and 3 connectors of same ports. (USB3 contains USB2 contacts)
In fact I wouldn't wonder if PC refused to start with that connection.

So take the one connected onto same cable as usb3 and plug the other one in?

Or only plug in usb3 and sdcard?

One pair of ports needs only one connector attached.
USB3 header cable being incompatible with USB2 header they just needed "adapter system" for those with only USB2 motherboard to avoid case being limited to one USB port.

I fitted the USB3 port, the SD Card port and the spare USB port header and all seems to be running ok. I think because the case has the ability to turn off the LEDs in the front of the case maybe thats what the extra USB port was for..
