Hi all, I have a probelm with my Mpman MID7C 7" Tablet (this one: http://www.mpmaneurope.com/en/products/internet-tablets-14/internet-tablet-mid7c-216): when I plug in a miniusb keyboard the display of the tablet freezes and after few seconds it shuts down. I tried with two different leather-case keyboards both Sapac T07-30 (this one:http://high-tech-e-shop.com/en/pc-portable/254-cover-10-with-integrated-qwerty-keyboard.html) whith the same result. I can say that both of the keyboards work fine when connected to a pc so I suppose they are not broken or else, and the teblet works fine if I connect i.e. to a usb mouse (I have only ps2 keyboards I I cannot make a test with another usb kyboard..) in its OTG miniusb port. The keyboards have a miniusb cable so it is not a matter of wrong adapter it connects directly to the tablet, they just don't want to communicate...any ideas?
