I had my 34972A communicating awhile back but now the Agilent Connection Expert (ACE) indicates "there was a commuincation failrue" and the error is "The instrument failed to return an IDN string".  I can no longer communicate with the instrument through my code or Agilent Interactive I/O.  I have uninstalled and reinstalled ACE...  when reinstalling ACE the first time it indicated there were other VISA drivers.  I uninstalled all that I coudl see (NI and TEK) and then reinstalled ACE...  still no go... any suggestions?
