about Labview and GPIB

[cantata2014]

It is a GPIB-USB converter, and connected to a power meter. under 'VISA resource name', there is no port for GPIB.

I updated the version of NI-488 and NI-VISA to the latest version. But the problem didn't change. 

Is this a hardware issue or didn't I forget to configure something?

then I checked NI-MAX. under 'Devices and Interfaces', it keeps searching. in one second, GPIB appears. in the next second, GPIB disappears. And repeats this situation.

this is GPIB. the state keeps changing between 'ready' and 'active'.

is this a hardware problem or did I forget to configure something?
