Dell e4300 bluetooth adapter not found. [SOLVED]

Hello gents,

I've got a problem with my bluetooth.

Dell wireless 365 is not shown, missing driver?

The bluetooth device is seen as a usb hub, for some HIDs. After some research i found out this is because in some cases the bluetooth device is set as a HID to allow keyboard and mouse to connect even if the system doesn't support bluetooth. To be used as a standard bluetooth device by the bluetooth stack ( eg. bluez ) it should be switched to HCI mode.

i tried this command but there's no device ( i tried just in case blindly throwing in hci1, hci2 etc hoping something would change but nope ).

12:54 faceless ~ $ sudo hciconfig hci0 up
[sudo] password di faceless: 
Can't get device info: No such device

I also tried using hid2hci utility provided by bluez-utils package but it ask for "sys device path" and i have no idea how to fetch it.

The strange thing is that the bluetooth LED is on.

All attempts to find bcm2046b1 or dell wireless 365 bluetooth drivers online have been unsuccessful, only found windows versions.

Also, i know there is a way to solve this problem: if you have a dual boot you can boot in windows, install or update the bluetooth drivers from there and when you come back the device is recognized ( work with a virtual machine too ). The problem is, i don't dual boot and i refuse setting up a virtual machine every reboot just to have the system recognize the bluetooth.

I'll keep digging on the matter, maybe something will come up.
Any suggestion is welcome, if other dumps are needed ask and you'll be given.

Cheers!

EDIT:

I just rebooted the machine and now it seems to be working properly, it is recognized and everything works.
lsmod shows that btusb and rfcomm are now loaded.
lsusb shows the Dell Wireless 365 is now recognized.

I sincerely don't know what happened nor what i changed. Stupidly i tried too many things before rebooting so i can't really pinpoint the cause.

The thing that i remember changing explicitly was adding a line to /etc/dbus-1/system.d/bluetooth.conf:

<!-- This configuration file specifies the required security policies
     for Bluetooth core daemon to work. -->

<!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-BUS Bus Configuration 1.0//EN"
 "http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd">
<busconfig>

  <!-- ../system.conf have denied everything, so we just punch some holes -->

  <policy user="root">
    <allow own="org.bluez"/>
    <allow send_destination="org.bluez"/>
    <allow send_interface="org.bluez.Agent"/>
    <allow send_interface="org.bluez.PasskeyAgent"/>    <------- Added this line here.
    .....
    # other stuff
    .......
  </policy>

  <policy at_console="true">
    <allow send_destination="org.bluez"/>
  </policy>

  <policy context="default">
    <deny send_destination="org.bluez"/>
  </policy>

</busconfig>

EDIT 2:

I add the links to the threads where i found the solution, since there were some more possible fixes if others have my same problem.
