This can be debugged using the article below:

I had a look at that link and it didn't really help. I've attached some information when the drivers are working compared to when they're not.

Like I said, it will always work after a restart but once unplugged and plugged back in the LAN and monitor will not work; looks like the USB3 bus becomes undetected.
Does anyone have any other suggestions?
