Converting USB 3.1 Gen 1 signals to USB 3.0 interfaces
Converting USB 3.1 Gen 1 signals to USB 3.0 interfaces
There are options to change a USB 3.1 Gen 1 header to a USB 3.0 header. For your setup, you can find a cable that supports the conversion. To split the header into two, look for a dual-headering cable. Your Aorus z390 Pro Wifi board already has two USB 2.0 and two USB 3.0 ports, along with audio inputs/outputs—just ensure the cable matches the available headers.
The conversion from 3.1 to 3.0 likely involves rounding down or adjusting the value based on specific criteria.
