thanks for your answer
yes i know, that it is a problem. But the main problem is, the chuwi Hi1 is pronounced with the possibilty of SDcard add on function, and i have as same selled to my customer. And he says to me, i give back to you the HI12 or you make it tready for this, or you give me back 30% of the buyer price. That is german law.
And when it is a known problem, it ist the mainly work for CHUWi to resolve this problem , or not?
Gernerally is to say, the SDcards, i tried, are working in my SD-Card Adapter at the microUSB-Slot very well.
And i did not find a nre driver for windows, some one in intrnet tell, to use a older driver for windows 8. I have also installed the Intel driver Utiluity-manager from the intel home page. . But this programm only find a new driver for the scrren. ( i have not installed at time, perhaps the screen will be black for ever or other, aftter install.
