So I've been having trouble getting windows updates to configure so I've spent a lot of time in BIOS lately messing with boot sequences. I kept noticing the my printer connected via USB kept getting put as boot device number 1, no matter how I arranged the sequence and saving it, even disabling boot from other device. The next time I'd go back in the printer would be back at 1 and boot for other devices would be enabled again. Trust me, I saved setting every time before exiting, any reason the BIOS would be doing this?
