USB 3.0 ports do not detect connected flash drives at start up (both in BIOS and Windows/Linux) but once I unplug and plug back in they work perfectly at full speed. This rendered booting from USB impossible (since BIOS only detects at start up) and everytime I plug in a flsh drive I have to re-plug it before it works.
