AT200-101 USB OTG strange behaviour with all devices
I've got an AT200-101 with an updated ICS 4.0 OS and I can't get the USB-hostmode to work. After a lot of reading about the fine difference between the regualar (type B) USB connector and type A (known as OTG) I finally have got the right adapter (it has a recangular shape and the ID-pin is grounded).
Now each time I plug in a device (usb massstorage device, 3G modem) nothing happens except the AT200 suddenly shows charging even though it's not connected to the charger nor is the connected device externaly powered.
I tried these external USB devices with an other ICS tablet (Zenithink) and they work fine.
