Why does it "compete"?
Is it because this driver also exposes a cdc-acm class interface?  Why
is it doing that if it doesn't follow that spec?  We do already support
a number of "quirks" in the cdc-acm driver, I don't see why we couldn't
add a "blacklist this device" one there as well to help you out here if
it's needed.
