Can' t recognize NI cRIO 9039 in NI Max

Go to solution



In my setup i have a communication between a Variable Frequency Drive and a PC by CAN/USB communication , and some readings of values between PC and a NI cRIO 9039 (via USB). 


Last week i had a shortcircuit in the Variable Frequency Drive and due to the bad isolation the PCs communication port died. Now, i have another computer and when I connect the NI cRIO device it says that USB device can't be recognized. 

I've also tried NI MAX program but it doesn't detect the controller.


I don't know if this issue is generated because some drivers are missing or because the cRIO USB port migth got burnt.


Any ideas what can be?


Thank you

To be able to communicate with a cRIO, your computer needs to have the CompactRIO driver software installed.


Depending on what other software you use to access the cRIO, you may have to install a specific version of CompactRIO.


You could try to connect your cRIO-9039 through Ethernet instead of USB. If it can be found and recognized that way, your computer has the necessary CompactRIO software and the possibility of a damaged USB port is very likely. But before you can find the device (or a different cRIO device) through Ethernet, I would first make sure you have CompactRIO properly installed.
