After obtaining an Orico A3H7 USB 3.0 hub with (sufficient) power supply the reproducability of the bug got limited to the broken HDD (reproducability with it is 100 % (disk is recognized by gparted and doesn't have a /dev/sdxY file)). Failure of of ethernet adapter no longer occurs which makes me think the original issue was related to insufficient power on USB connections and that the error `xHCI xhci_drop_endpoint called with disabled ep` is related rather to a consequence of the power failure rather than being the error of the power failure.
In my point of view it'd make sense to get the HDD working again (there's probably an issue with the partition table) and testing whether it works in 3.13.0-36 and then other versions (including mainline).
