if i do hcitool dev, nothing shows.
if i plug in a usb dongle bluetooth, it shows correctly.
But interestingly, w/ the dongle in, and i run 'hcidump', it sees the on-board bluetooth:
00:0D:18:A1:29:2F CAR KIT
hciconfig shows no devices w/o the dongle, but does show the dongle when plugged in.
with the dongle plugged in the '/sys/class/rfkill/rfkill0/state' is populated.
In neither case is the settings menu showing any bluetooth menu item.
