The acx module also loads all by itself, but complains about missing

Ok, next step I guess is trying to find that firmware image 'tiacx111usbc1B' on
the temporarily appearing pseudo CD-ROM drive or on the real CD-ROM that came
with the device. Trouble is I don't really know what I am looking for. The
real CD-ROM contains several instances of a file named Fwusb1b.bin, could that
be it? And if so, where should I copy it so that the acx driver will find it?

Try with that one, copy to /lib/firmware, if it doesn't work try with
the one from [1].
