yesterday i finally tried using a bluetooth headset and after somen hassle
(the comparatively expensive headset HBH-DS220 from sonyericsson can only
handle one paired evice at a time, once you get more you have to repair it
every time ... crap; a cheap, in fact free, jawbone PBH-8W can handle at
least two, if not more).
anyway, after trying the aforementioned PBH-8W i was able to hear my own
voice in call, but the other side couldn't hear me.
since i hadn't used it a long time i wasn't sure if the mic was somehow
damaged and tested with another computer, to make sure it was ok, which it
was.
coming back to the fr and resuming it i noticed that bluetooth was gone.
symptoms and what i have tried last night:
# hcitool dev
does not list any device,
# mdbus -s org.bluez
does not list any of the devices known (two different headsets).
restarting bluetoothd did not change anything.
doing
echo 1 > /sys/bus/platform/devices/neo1973-pm-bt.0/reset
echo 0 > /sys/bus/platform/devices/neo1973-pm-bt.0/reset
does not change anything
requesting the resource works (at least returns 1)
releasing returns an error
even after shutting down bluetoothd and frameworkd, i can't remove the
modules bluetooth and btusb, btusb has always a use count of two, but not
other modules are listed
