Hardware USB 3.0 port doesn't read usb 2.0 on Zalman Z11 Neo

[Flirkyn]

Hello poeple
So I just made my own rig (my first one ^^) and everything seem's to work nicely ! Except for one problems : my case are a Zalman Z11 Neo. I have 4 usb port on the top, 2x2.0 and 2x3.0. 2.0 port read normaly device on 2.0 and 3.0, but 3.0 port read only 3.0 device (it give power to 2.0 device, but the computer doesn't recognize it). I have no problem with 3.0 device (except for my phone (Galaxy S5) who is not recognize, certainly because the default mode are not 3.0). Is it normal ?
The 3.0 port on the motherboard read both 2.0 and 3.0 device. Driver seem's up to date.

My configuration if it help :
-Windows 10 Pro
-Motherboard Gigabyte GA-H110-S2H DDR4
-2x8GB Ram Corsair DDR4
-AMD RX480 8GB
-Zalman Z11 Neo

Thanks for the help ^^

Not all USB 2.0 devices function properly on USB 3.0 ports. I'm not sure if it's controller drivers or device drivers that cause the issue. Some USB 2.0 devices only function properly on USB 2.0 ports.

Unplug the 3.0 ports from the motherboard and plug them back in. Took me months to finally get mine working because the header is loose for me (stupid design imho).

Well, they are recognize by the 3.0 port on the mobo, so I think they can work

It seems to been that ! Now it's working ! Thanks !
But, it's strange that it was working for 3.0 device...
