This is an odd one. I have two laptops (on an estate of 250) which won't recognise the USB ports on the docking station.
Have swapped out hardware, and tried the disks in a new chassis and it is down to the disk.
So far so normal - must be an OS issue, right? Well that's where it gets weird.
The USB issue also manifests at BIOS level (i.e. you can't move around in the BIOS with a USB keyboard connected to the docking station) and on an Ubuntu image booted from USB.
Don't think it's necessarily relevant, but they are Lenovo T431s laptops, on a Mini-Series Plus Series 3 (4338) docking station.
