Commander Pro not showing up in ICUE

[cam1126]

For reference, this is the diagram I am using but the QL's are LL120s and the ML120's are QL's. As well I am not using the AIO due to MOBO problems. So pretty much the issue is I only have one USB on my MOBO so I have a USB splitter. I have the commander core plugged into the commander pro but when I plug the commander pro into the MOBO the commander core doesn't show up in icue, just the commander pro. But if I plug the commander pro into the USB splitter only the commander core shows up and not the commander pro. How can I get both of them to show up in ICUE?
