Description

Description from Bal√°zs:

AFAIR, the USB3 ports were really problematic.
Most of the time it was really slow, somewhere around USB 1.x speed.
The only way to have the ports properly working to reset the motherboard with the coreboot bios chip in, while the factory bios was loaded. And this way somehow the old fw remain in the controller and the ports were fast as they should be.

So, first thing to check the xHC firmware version used by the vendor firmware. coreboot uses version 1.0.0.48.
