Why not look a the manual (.PDF), it does have 1 port on the Mobo that connects 2 USB 3.0 devices.
Here is an example:
![32573 32573](/t5/image/serverpage/image-id/23265i63482E980A9BCCC0/image-size/large?v=v2&px=999)
That Blue port can connect 2 separate devices using a splitter like this:
![32574 32574](/t5/image/serverpage/image-id/23264i9C1CB0728865780D/image-size/large?v=v2&px=999)
What does not exist is this mock up a peep made :
![32575 32575](/t5/image/serverpage/image-id/23269i21D26E67C82F6A15/image-size/large?v=v2&px=999)
I ideally need one of those if it existed but it would only allow 1 device to work at a time which is fine as it would let me connect the USB 3.0 ports on my case and my front Panel at same time but use only 1 at a time which is fine by me.
I am not sure why this is the case because AFAIR old USB 1.0/1.1 you could daisy chain 127 devices from 1 port using hubs, no doubt its to do with the handshake and the devices being given a ID which may not happen if multiple devices are on 1 port, no clue TBH.
