it looks like it is actually setting it up as ttyACM0

It should not be necessary to tell the kernel to use another device,
but you do need to figure out which one was used. Then tell the
arduino app which one it should use, but it normally detects it pretty
well.  You may be hitting some other issue, why do you think it is
trying to use the wrong device?

Well the common way is to look at the logs as you did, you can also
look around in /dev and see which devices are available.
