Hi.
I have a problem with this Mobo. I have several rigs with USB with linux like SO. Sometimes when a rig hangs and reboot  the mobo enter directly at BIOS continously and don't recognize USB pendrive.  The only solution is change pendrive of USB port and mobo restart without problem. This is a problem for to restart the rig remotely.
Why happend this? What is the solution?
My config is:

Asrock H110  pro BTC+
Celeron 2.9 Ghz
4 GB Ram DDR4
12 RX570 8GB
3 Nox Hummer 850W
Pendrive 16GB USB3

Thx.
