A485 and Thinkpad Ultra Docking station USB issue

2018-12-28, 18:39 PM
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:

Re:A485 and Thinkpad Ultra Docking station USB issue

I had this same issue. The solution was to install windows and update the firmware to the docking station. Then remove said virus and reinstall or swap the hard drives back. I tried this update from several USB bootable windows usb's but the do not work to run the firmware update on the dock as the update is done on windows reboot. sadly they list this laptop as linux ready.
