Hi Guys, Very simple -- My Machine: ASUS BIOS [3/18/2018] for ASUS Maximus hero VIII [Z170 chipset] w/ 6700k ISSUE: Computer powers-on to POSTS 2 times, when I have both my Razer Naga Epic + Razer Firefly inserted in USB ports. Doesn't matter which ports, which HUB any combination of USB 2.0 / USB 3.0. If I leave the razer firefly unplugged, my machine POSTS once, then into Windows 10 and so on. Yeap, its rather obnoxious. If I leave things as is with both peripherals inserted, at some point [2 days out of 14], my machine will fail to POST entirely with Qcode 64, which usually indicates a generic USB-Hub issue/device issue.
