I have a GPIB-USB-HS that was working for years but recently stopped working. When I plug it into the computer, the "active" light will be on for ~5s (even though nothing is connected to the GPIB side), and then the ready light will blink once, and then both lights will be off and never turn on. When I looked for the instrument on NI MAX, I was able to find the device under Devices and Interfaces. However, it can only read the serial number when I click on it and does not show any of the bottoms for me to control it(the reset button, test button, and all others are missing). Has anyone seen similar issues before? Is there a way to fix this issue?
