My MoBo only has 1 USB 3.0 header, however my case has 4 USB 3.0 ports meaning I need 2 headers.
Rather than splitting the single header I'm wanting to plug one of them into the two USB 2.0 headers. I don't mind downgrading 2 ports to 2.0, i likely won't notice the difference.
are there any adapters that would allow me to do this and would it be better to split the 3.0 cable between both of the USB 2.0 headers or just plug them into one?
