I found downloadable drivers and firmware quite handy in the past as a fall-back option in case the one bundled with the OS didn't work properly (had to do that once or twice, but that was something like 10y+ ago). > The last time they added PCI IDs to the mpr(4) driver was in December > 2018.

I had looked into the source tree of the mpr driver in 13.0, but somehow failed to find references to the 3808 chipset (just had looked for "3808" as a string, which isn't there, in contrast to 3816 - but maybe that was a too shallow idea on my side :-). The 38* chipsets also aren't mentioned in the mpr manpage at all - maybe that one isn't up-to-date then (although it claims to be from June 1, 2019 here)? cu Gerrit --
