GPIB通过Agilent 82357B连接到PC无法工作

嗨，我正在使用由7到8个仪器组成的设置，通过GPIB通过Agilent 82357B（USB / GPIB接口）连接到PC。
它之前一直很好，但是当我从假期回来时，我再也无法工作了。
导致的失败一直是红色的。
故障似乎与82357B本身有关，因为我在不同的PC上尝试了适配器而没有运气。
已将IO库重新安装到最新版本，断开所有仪器，重启几次等等。我再也不会变绿了。
在我缺席期间，我唯一知道的事情是17个新的Windows更新（Win 7）。
这是我在软件方面唯一可以想到的可能影响的东西。
我想这是硬件或硬件。
然而，据我所知，没有其他人触及过这个设置，所以很奇怪..任何有类似经历的人？
所有的帮助表示赞赏，因为这是紧急的。

  Hi,  

I'm using a setup consisting of 7-8 instruments connected through GPIB to a PC via an Agilent 82357B (USB/GPIB Interface). It has always worked fine before, but when I got back from my vacation I can't get it to work any more. The fail led is constantly red.  

The fault seem to be with the 82357B itself, as I have tried the adapter on a different PC with no luck. Have reinstalled the IO Libraries to latest version, have disconnected all instruments, rebooted several times etc. I just won't turn green again.

The only thing I know happend during my absence was 17 new Windows updates (Win 7). That's the only thing I can think of on the software side that possibly could affect. It's either that or broken hardware I guess. However, no one else has touched the setup either as far as I know so it's strange..  

Anyone with similar experience? All help is appreciated as this is urgent.
