I've been trying to use an usb bluetooth adapter, but all the instructions I found on the internet have not worked.
I'm running Ubuntu 14.04
A brief description of the problem:
lsusb does not list the dongle, even though it is connected.
hciconfig -a produces no output whatsoever.
rfkill list also lists nothing.
I've tried reinstalling the bluetooth related packages, by running
sudo apt-get install bluez bluez-alsa bluez-audio bluez-btsco bluez-compat bluez-cups bluez-dbg bluez-gstreamer bluez-hcidump bluez-pcmcia-support bluez-tools bluez-utils python-bluez bluewho indicator-bluetooth libbluetooth-dev libgnome-bluetooth11 libbluetooth3
(bluez-dbg is probably overkill, though)
and I've tried adding
rfkill unblock bluetooth to the /etc/rc.local file.
None of these have worked.
After trying to use it on another computer, running Windows, the system was seemingly unable to properly use the device. It seems like the device itself is broken. Thanks for the help.
