I figured i would come here and tell a quick story. From my early findings, leaving a PS4 controller plugged in will mess windows' boot sequence and will freeze at the windows logo. When it happens, Q-Code "B1" is shown on the motherboard. Upon disconnecting the PS4 controller, everything returns to normal. I thought it could be usefull if someone encounters this issue. I haven't tried messing with the "xHCI" settings in the bios neither have i tried to use another usb port. I've used a Front 3.0usb port and the bug happens. I will not invest more time into this since fixing this only requires you to disconnect your PS4 controller before booting and reconnect it when you're in windows.
