The RPi3B has 5 USB ports for devices, one being internal
that is tied to the EtherNet port if I remember correctly.
It also has a root hub,6 six overall.

Your failure log is about failing to get the root
hub working --which in turn blocks all the other
ports form being accessible.

I'd also recommend recording a bunch of failures
and seeing what wort of variety exists in the
details of them.

FYI: My log shows a Root Hub Port 1 status
sequence: 511, 511, 503. Yours: 311, 311,
(5 times:) 301. So it looks like what the
status encoding is and what the implications
