So whether this is only my and I got here a "Monday" version, I can not answer, and I do not know if and how quickly the support responds to them, so 1 star because at least it remains dongle pleasantly cold what many others can not be said ...
================================================== ===============
ADDENDUM:
So the support leaves nothing to be desired. A day later, a new dongle was traveling and worked right away properly (was empty and only with SD stocked recognized immediately). Also was again pointed in the response to the 18 months warranty.

Conclusions:
---------------------
Now, when I look at me the result, it is clear that a real parallel use is not possible, because it is clear that an clocked / sequential access to the respective card (and obviously win the first device (ie SD) have at least I when the test first initiated).
All in all now in the knowledge of the little weakness of the reader and to the good support 4 stars (instead of initially 1nem) for the part!
