Hello,
I am currently using a USB-6009 and another device connected via USB using a virtual COM port. These are connected to the computer using a 4 port externally powered USB hub. Everytime I run the VI I get the following error:
Error -1073807343 occurred at Property Node
(arg 1) in VISA Configure Serial Port (Instr).vi-
>MI3 Read Temp.vi->SagDAQ.vi
Possible Reason(s):
VISA: (Hex 0xBFFF0011) Insufficient location information or
the device or resource is not present in the system.
After this error I must unplug and reconnect the device to use it. I have installed the drivers that came with the device and if I use the supplied software the device came with I have no problems with the device at all.
I have also noticed that if I do not use the USB hub there are no problems either, however I need to use the hub for this setup as ports are limited.
I have this device being used in multiple parts of my VI, however everything is running in series and all instances are ended by closing the VISA resource. If I just open one of the sub-VI's that calls the device I can run it indefinitely with no problems on the hub, but for some reason when I use them in the main VI I get this error.
Has anyone else had this sort of problem or know how to handle it?
Thank you!
