Function zero in Galaxy Tab 2 10.1 P5100 3G

Unfortunately, the adapter works with my Samsung Galaxy Tab2 10.1 P5100 3G
Not at all.
I tested the following components:
USB Sticks: Kingston DTR500 16GB FAT32
Kingtstion DataTraveler 100 G2 16GB FAT32
Spaceloop 4GB FAT32
And San Disk Micro Mate SD card reader with a Panasonic SDHC 4GB SD Card Klass4

Versions to connect the sticks:
Only USB adapter to the TAB and then the USB flash drive to the adapter: No function
Only USB flash drive connected to the adapter, then connect the adapter to the USB stick to the Tab: No function
Galaxy Tab with adapter and USB Stick restarted: no function.
No components listed by the work with the adapter on my tab.
As a wrote, for EUR 3.45 am I doing here also no elevation to return to send. But the mass makes it possibly, where it does not work, then do not send it back.
From me there for my Tab and my components NOT BUY recommendation for this product.
