Alexander Sack, as per http://download.lenovo.com/express/ddfm.html an update is available for your BIOS (1.38). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Thank you for your understanding.

** Description changed:

- Hi,
- 
- setup:
- 
- 1 USB Hub with 4 ports, connected are:
-  - keyboard
-  - mouse
-  - yubikey
-  - webcam (not in use)
- 
- the hub is powered.
- 
- Since recent kernel the hub suddenly powers of the ports and i need to
- replug it.
- 
- I ran ubuntu-bug linux in the  hope this captures anything useful.
- 
- Will reboot with previous kernel that didnt expose the problem to see if
- this is potentially a hardware issue..
