Hi everyone.
I m new in Labview.
I want to connect my pyrometer to PC.
I made COM-USB connector. Made small programm in Labview. Check attachment.
First time I had no problem.
Then, appeared such mistake:
Error -1073807343 occurred at Property Node (arg 1) in VISA Configure Serial Port (Instr).vi->Untitled 2
Possible reason(s):
VISA: (Hex 0xBFFF0011) Insufficient location information or the device or resource is not present in the system.
Now I found out only 1 decision: reboot PC. But, it's spent a lot of time.
Question: how I can solve that problem without rebooting PC? Maybe need to reboot usb? But, cannot find information how to do it.
Thank you in advance

Welcome to LabVIEW and the Forums. As you know, a LabVIEW program is a little different from other languages you may know. In particular, we can provide a lot more help if you attach the LabVIEW code (which is easiest to do by attaching you VI) than if you simply show a picture (as you did).
The picture you attached is woefully tiny, and incomplete. Have you looked at any of the VISA Examples that ship with LabVIEW?

Your issue sounds like the USB hub on your computer decided to turn off. This is a power saving "feature" of Windows as of Windows 7. I recommend you turn that off.
Also, you really should make sure you close your VISA session. Otherwise the computer will think that the port is still being used.
