Dave and Roel, Thank you very much for your quick and informative responses. Dave: I ran the lsmod | grep gpib command, and didn't see anything. Roel: In conjunction with Dave's response about looking at the console log, and your keying in on the depmod issue, I paid better attention when I ran the sudo make install command on the linux-kernel stuff. I missed an important error about a missing System.map file After poking around a bit, I found out I had the two following directories: /usr/src/linux-headers-5.0.0-27 and /usr/src/linux-headers-5.0.0-27-generic The first one had a symbolic link from System.map back to /boot/System.map-5.0.0-27-generic, while the second directory did not. So, not really knowing if it would work, I created the symbolic link in the /usr/src/linux-headers-5.0.0-27-generic directory. I then did the make, sudo make install on the linux-gpib-kernel stuff and that error went away. I now get the following when I run the lsmod command lsmod | grep gpib ni_usb_gpib 36864 1 gpib_common 45056 3 ni_usb_gpib I have edited the 98-gpib-generic.rules file for the two different NI-USB-HS devices that I have based on serial number, and when I watch the logs they are attaching to the correct bus interfaces (0 or 1 depending on the serial number). >From what I can tell, things appear to be working. I wouldn't have reached this step without your assistance. Thank you!

I'm struggling with installing linux-gpib-4.3.0 on Ubuntu-18.04LTS and getting a single NI-GPIB-HS controller to work (and I need to run two at the same time). Has anyone had success doing this?

I saw something on the output about SSL errors, but things were created in the /lib/modules/kernel_version/gpib directory so I thought I was okay.
