I am struggling to get my bluetooth adapter work on my Linux desktop.

I see it when I plug it in, but basically, nothing else works correctly:

$ lsusb
Bus 002 Device 006: ID 0a12:0002 Cambridge Silicon Radio, Ltd Fontline     
Test Equipment Bluetooth Device

I can't put it up:

$ sudo hciconfig hci0 up
Can't init device hci0: Cannot assign requested address (99)

Bluetooth service is not working properly and can't be started:

$ sudo service bluetooth status
bluetooth stop/waiting
$ sudo service bluetooth start
start: Job failed to start

The logs say : "init: Failed to spawn bluetooth main process: unable to execute: No such file or directory". There are also plenty of :

[ 5485.753603] init: bluetooth main process ended, respawning
[ 5485.776272] init: bluetooth main process (24531) terminated with status 1

I tried to re-install bluetooth, blueman etc. They depends on the bluez package, and one of the issues(?) seems to be that I fail to install bluez.

$ sudo apt-get install blueman

In this question, I saw mention of bluez-firmware, but couldn't find that yet.

$ sudo apt-get install bluez-firmware
E: Unable to locate package bluez-firmware

In attempts to solve the issue, I upgraded my system to the latest Linux Mate 17.3 Rosa + upgraded the kernel to 4.4, however this does not solve the issue.

I have been reading tons of more or less similar issue, but could not find the answer :( Thanks for your help!

I guess you could try a few things:

1) Try to reboot your PC to see whether it could be due to a hotplug / coldplug problem

2) A bug on the kernel Linux affecting similar dongles has been identified, and patched, see bugzilla, so updating your kernel might be the best option for you.

  • I rebooted, and unfortunately confirm it's not a hotplug / coldplug issue as it's still not seen if I reboot with it attached. I'll try upgrading my kernel.

  • I upgraded to kernel 4.4. That didn't solve the issue. I still can't use hcitool etc. And bluez still won't install. So, consequently, bluetooth, blueman etc don't install.

  • Same problem with the same bluetooth dongle (exact same model, including the USB vendor-id and product-id), but on Fedora, exact same problem, can't get it to work with hciconfig hci0 up, etc.
