But then I wanted to submit a blacklisting patch for the Infineon
flashloader device to avoid that noise, and things started working....

I guess that is not as expected, but it seems that part of the issue is
this single serial port which briefly appears while the modem is booting,
of course connected to exactly the same USB port as the composite MBIM
and ACM device later appearing (with a completely different ID).

Patch and log attached.  Hoping you can make some sense out of this.

BTW, if anyone has any tips on how I can actually use this flashloader
device then I'm interested in that too :-)
