   Good question. According to
https://www.asus.com/Notebooks/X555LA/specifications/ , this machine
has two USB 3.0 ports and one USB 2.0 port. Does the USB 2.0 port work?

   Not having full USB 3.0 support is IMHO a serious black mark against
NetBSD on modern hardware. Is anyone actively working on it? Are there
particular known obstacles? I could perhaps spend some time on it
myself if pointed in the right direction.
