Hi,
I am having an intermittent problem with a GPIB-USB-HS+. It hangs very occasionally in a call to VISA. The timeout on the call has already expired for a long time, so my first thoughts were that it's a driver issue. However, upgrading from the 2014 drivers to the latest ones did not help.
I have now replaced it with a GPIB-USB-HS (without +). So far it works well. Has anyone else seen this problem before, or am I just having a faulty device?
Best regards,
Joris

I've had this sort of problem with the GPIB-USB-HS Win7 + Win10 when I haven't disabled the USB suspend settings disabled. Here's how to disable USB suspend - https://helpdeskgeek.com/how-to/prevent-windows-from-powering-off-usb-device/
Its a real pain. I moved from a WinXP to Win7 system and re used existing code that had run for years. But it mysteriously failed at odd times. I switched to a PCI GPIB card and it worked...that's when I started to blame the USB ports and found the solution.
Hope this helps.

Well, after the replacement of the GPIB-USB-HS+ with a GPIB-USB-HS not a single hang has occured since.

I have the same problem with a GPIB-USB-HS+ as compared to a GPIB-USB-HS.
The problem is "solved" if the NI I/O Trace is running at the background.

What does this mean or how do you set up the "NI I/O Trace running in background"
The problem is "solved" if the NI I/O Trace is running at the background.
Same problem here. GPIB-USB-HS always works but GPIB-USB-HS+ and GPIB-PCI will hang-up and not be responsive after 2-3 days.
