After publishing my detailed review of the motherboard, I have figured out a few more important facts:

  • Even though the BIOS on Huananzhi X99-F8D is blocked for FPT, it’s possible to flash the BIOS with AfuDos. Compatible AfuDos version as well as the original BIOS can be downloaded from the official Huananzhi website.
  • There is an alternative USB 3.0 driver, which resolves issues with the ports.

The USB 3.0 driver and X99-F8D BIOS with compatible AfuDos can be downloaded from my OneDrive.
