I just upgraded my old ASROCK Fatality MB to a newer MSI Gaming Pro Carbon x470, and have discovered a horrible crippling feature. I can only attach two USB 2.0 devices to each internal USB 2.0 header.
Even self powered devices like the Lighting Pro are not recognized if there are more than 2.
I have 2 USB 2.0 headers on the MB, and way to many corsair devices.
Corsair H1200i PSU (it was only $109 open box on Amazon, don't judge!)
Corsair Commander Pro
Corsair Lighting Pro x 2
Corsair Gaming K95 Platinum
Corsair Dark Core RGB
Fans LL120 x 5
LL140 x 3
RGB Strips x 8
On my ASROCK MB I had attached a 1 x 4 unpowered USB splitter, but that simply doesn't work with the new x470 MB.
Has anybody else encountered this problem? I am considering as a work around purchasing the NZXT powered USB 2.0 splitters, but hate to do if it a powered splitter extra headers are not going to be recognized by the motherboard either.
