For the Acer Nexus 7, it just does not fit. Because there the micro USB connector is on a sloping site, you can not push enough micro USB part of the cable in the Tab pure. It there is no connection to the USB stick on the other side of the cable. I thereupon the plastic around the metal part from filed. So I can fully insert the wire into the tab. Since then it works as expected and described.
So whom do not mind einbisshen tinkering, it can still use.
