OK ... but what is it? Is it described in the guide?

Thanks.

   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.

Any idea to make USB work? Standard speed USB would already be sufficient.



Hmm, no EHCI device at all? Maybe experiment with the various USB 
settings in the BIOS to see if you can get an EHCI device to show up.


(Of course, you can also try a kernel with the xhci driver, but as the 
comment says, it's still experimental)
