Trying (very) to install Samsung ADB interface to connect to Android Tablet via OTG cable and for some reason tablet has lost its plug and play. Here comes the catch 22 situation Can not update firmware or reinstall firmware without ADB interface so well and truly screwed.

I have tried other drivers but cannot get them to work. Also tried delete, restart,reinstall,remove driver restart reinstall

Every one a loser.
Can anyone suggest how I can get the darn thing to work please.
Using Windows 7 Home Premium with SP1.
Had thought of trying Virtual pc but not compatible needs win 7 Pro or better so screwed again.
Best wishes to all
Keith
