I have an USB drive with UEFI OS image and successfully installed OS using it.
But when I tried to boot from this USB drive for the next time it just gone from boot menu and from list of bootable devices in visual bios.
I used the front panel USB to install OS but after that I've tried to use some of USB ports on back panel and after several attempts ALL of my usb ports stopped to recognise USB boot drive.
But ports itself are working fine. When I boot into OS peripheral works fine and I can even access data on the pen drive attached to the front panel USB.
Also usb keyboard and mouse connected to same ports working fine in Visual BIOS. So this is not a hardware issue I guess.
BIOS version is 0049.
