Serial port enumeration Ubuntu 24.04.2 LTS

[Bilsix]

Hello all,

I need to use LabVIEW under Linux, I use LabVIEW 2025 and the OS is Ubuntu 24.04.2 LTS.

I'll need to communicate via a serial port with another module. i installed NI-VISA but when I try to run a LabVIEW example, the enum of the VISA resource name is empty, even if the COM port is plugged and available via the Linux Terminal.

I'm (clearly) not a Linux expert, so every help or brainstorm'll be helpful... 

What did I miss ? Which package didn't I install ?

Thanks in advance !

Found it !

It took me a day but the issue came from ni-serial and/or ni-visa was not correctly installed.

To solve it:

1. Uninstall LabVIEW from Ubuntu

2. Reinstall it

3. Reboot

4. After the installation of LabVIEW, install .deb from NILinux2025Q2DeviceDrivers (the ni-ubuntu2404-drivers-2025Q2.deb for me, not the stream

5. Reboot

6. Follow this link to install all the drivers you need (ni-visa, ni-serial, ni-daqmx, etc, a good list is here). You may need "dkms" package before all the installations.

7. After each package installation, reboot (that's what I did and I'm not disappointed)

Have a nice day,
