Dear All... I have also the same as above.
I've tried to use another iPad power adapter and it didn't work
I've tried to use another cable and it didn't work
I've tried to use another computer "both MAC and Windows" and it didn't work
I've tried different versions of iTunes " al 9.1 and above" and it didn't work
I've tried to restart/shutdown the iPad and it didn't work
so could the problem be from the iPad it self ? and what can i do about it ?
I have tried it in Mac Book Pro with old to latest version of iTunes. and also changed many cables and adaptor... bt didnt work properly not even shows up my device in both Windows 7 and Mac Book Pro.
Pleaseeeeee Help me.
