hm, https://wiki.debian.org/InstallingDebianOn/Asus/X205TA#WiFi
suggests:

   cp /sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113 /lib/firmware/brcm/brcmfmac43340-sdio.txt

and indeed, after doing that, and then removing and re-loading the
kernel module with:

 modprobe -v -r brcmfmac
 modprobe -v brcmfmac

then the device is found correctly.

     --dkg
