FINALLY! USB4 Worked On An AMD Laptop!!
When Gordon reviewed the Asus Zenbook S 13 OLED equipped with a Ryzen 7 6800U, he couldn't get USB4 to work. After some back and forth with AMD to get a newer BIOS, he was able to get it a whole host of devices connected -- including an eGPU! In Gordon's words: I S MYSELF WHEN USB4 WORKED!
