But what did not work: the adapter.
had 4 tickets ordered and logically therefore also got 4 adapter. In short, so every week one after another flew into the trash! was no longer recognized by the system as a mass storage. shame really, because just because of this Mini (USB 3.0) adapter cards were ever ordered. Why is not there the adapter individually to me now is completely understandable.
the adapters have been used in the way the IT organization in different (new) computers, so no old USB 1.1 crutch
