34972A USB通信失败

嗨，我让我的34972A通信了一段时间，但现在安捷伦连接专家（ACE）表示“存在通信失败”并且错误是“仪器未能返回IDN字符串”。
我无法再通过我的代码或Agilent Interactive I / O与仪器通信。
我已经卸载并重新安装了ACE ...当第一次重新安装ACE时，它表明还有其他VISA驱动程序。
我卸载了所有我看到的（NI和TEK），然后重新安装了ACE ...仍然没有...任何建议？
谢谢

  Hi,
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?
Thanks
