forget about all the chipsets that are not supported by Open Source drivers.
What one will want: are chipsets that work out of the box with Debian 10 Open Source Drivers!
actually have to praise AVM (or whoever contributed/did it) for releasing free (OpenSource) drivers for this WIFI Adapter. GOOD JOB!
WORKS LIKE A CHARM!
