About USB port identification

Hello everyone,

I’m planning to use 4 OMEGA MINI USB as temperature sensors in one station.
However, Tulip does not seem to be able to identify which USB port on the I/O Gateway the received information is coming from.

What I want is to use " if the information is from USB1, assign it to variable A, if it is from USB2, assign it to variable B… "
and so on.

I’ve asked the question again, please delete it.
Thank you.
