How to install multiple GPIB-USB-B

[shauna]

How do I install two GPIB-USB-Bs? I have 488.2.7 installed.

Plug them in one at a time.

I installed one, it was recognized and installed.  I restarted the computer.  I then installed the second it also was recognized and installed.  But when I open Measurement & Automation there is only one. When I go to device manager there are two installed.  What can I do to fix this?

Strange. I've never used the -B, only the newer -HS and pci cards and I have not seen this. I'm not sure what the problem could be. Do you have them plugged into the same USB hub?

Yes, I have tried every which way.  I take it the software is suppose to automatically install each one: GPIB0, GPIB1 etc.

That's what supposed to happen.
