Endless attempts to guide, to assistance, it does not go.
The tablet is the device simply does not. It will not be displayed.
We sent to a one-week test phase the device back and ordered a keyboard of CSL.
Lo and behold, works immediately, the detection is easy.
Unfortunately, I can therefore only awarded 1 star, pity, because the keyboard made a pretty solid impression.
However, not to be used for my use :(
