It was confusing when I use a VISA Find Source node to detect instruments connected to my computer. A VMIC's reflective memory card----VMIPCI5565---can not be found while it could function well with its own exacutable programme borned with driver. What's more worse,a VXI structure that copmosed of a HPE8491 0-slot controller and a HPE1412 Multi-Meter did not turn up either. And the VXI structure is connected with computer by a IEEE--1394 adapter which was ploted in a PCI slot.
SO , it is the problem related to hardware or some others? How to find the instruments that are un-NI products?
