A485 and Thinkpad Ultra Docking station USB issue

I have an A485 with the ultra docking station using ubuntu 18.04 and 18.10.

 

Whenever I undock the laptop, the USB ports stop working completely.

 

Docking or undocking does not help afterwords. Removing the USB and reattaching does not work. Adding a USB after the undock does not work. It's like the USB ports don't even exist.

 

The only thing that makes the USB ports work again is restarting.

 

I have upgraded the dock firmware, BIOS firmware and upgraded the kernel to the latest version to no avail.

 

Anyone have this issue or know of any fix? Thanks!

I ran the lsusb command before and after undocking and it shows less devices:
