sounds like glitchy hardware - have you checked to see if there are firmware updates for the laptop or docking station?
I had thesame problem with USB radio transmitter for mouse and with some USB sticks/flash-drives.
To solve this I disable option Always enable pre-boot USB support in Policy and for some laptops I disable BIOS option USB Legacy Support.
I had the same issue, but not with Lenovo.
In my case it was Dell Latitude. Udate BIOS fix it.
