Hmm, this smells like a bug in systemd.
Do you have any service file for this device installed?

Yes, but usually this should just fail with ENOENT and be ignored. For
some reason this generates EINVAL for you however.

That could actually be. Of course we should fix systemd to handle this.
I wonder how I could easily reproduce this issue here, without that hw.
My first guess is that i's actually the length of the name, and not the
contents of it that triggers the EINVAL.
