No ADB driver for medion e4001 (MD 98500) for remote debugging
I found a solution (for windows):


Download the official MEDION ADB driver for some other tablets they offer
Unpack
Open the android_winusb.inf file in a texteditor
Add the following lines at the end of the two sections [Google.NTx86]up and [Google.NTamd64]
;
;MEDION Life E4001
%SingleAdbInterface%        = USB_Install, USB\VID_109B&amp;PID_911E
%CompositeAdbInterface%     = USB_Install, USB\VID_109B&amp;PID_911E&amp;MI_01 

Go to the device manager, select the unknown driver (called generic in my case), update driver and select the folder.


Off you go!
