this doesn't seem to have anything to do with systemd, and it sounds like you're manually configuring the key, so it's not clear to me what the problem is. your manual configuration was removed after a kernel update, or something else?

I also attached my mouse to the same hub. On kernels up to 5.9, compose key (which I defined as Right Super/Right Win) worked for a while, and then did not work (no accented letter inserted when typing right sequence). For example, instead of à I got `a. On 5.10 kernel (I reported this bug using custom-compiled 5.10.1 kernel), compose key does not work initially. The workaround is to open Tweaks and redefine compose key to the same key.
