Adding debian-live@ for information.
TL;DR: For images generated by live-build, firmware lookup cannot rely
on Contents-firmware files (apparently not generated, I didn't check
myself), which leads to using a fallback that's currently buggy (lack of
support for /usr/lib/firmware in hw-detect's list_deb_firmware).
We're looking into fixing the latter, but you might want to address the
former as well? In which case, some debian-cd.git pointers:
