Having two separate @reboot lines might run them both in parallel,
rather than sequentially. It might be better to combine them into
one shell command, or one script.
Something like this, perhaps:
@reboot /usr/sbin/modprobe brcmfmac && echo 13b1 0bdc >
/sys/bus/usb/drivers/brcmfmac/new_id
Or put the commands into a shell script, then run the script from crontab.
