2021Q3 Drivers - PCI-6528 not recognized / Ubuntu 18.04

[Josh@IS4S]

I recently installed the 2021 Q3 NI Linux drivers on an 18.04 machine in an attempt to use my PCI-6528 card with Ubuntu. The ni-daqmx driver installs correctly, but when I run "nilsdev" I do not get any devices listed. I can see the device with "lspci". I have used the same drivers and card on CentOS 8 without any issue. Any suggestions on getting this card to work on Ubuntu would be greatly appreciated.

What does dkms status show you?  How about lsmod |grep ni?

The comedi driver has taken precedence over the NI driver.  You'll need to disable it somehow.  udev rules, maybe?

[Josh@IS4S]

I attempted to blacklist the comedi driver, but for some reason it kept loading. I decided to blacklist the ni_65xx driver to see what would happen and somehow this made things work. 

My resolution was as follows:

Create the file /etc/modprofe.d/blacklist-ni_65xx.conf with contents

blacklist ni_65xx

Then ran "sudo update-initramfs -u" and rebooted.

nilsdev now returns "Dev1" as it should

"lsmod | grep ni" now returns
