Bluetooth Dongle No Longer Active [Solved]

(1/3) > >>

Martin Goose:
I have been successfully using Bluetooth dongles with PCLOS for some time. Recently the dongle on my Acer Ultrabook no longer started up (flashing) when booting, although one continues to work on my desktop PC. Both are running fully updated PCLOS KDE. Kernel 3.2.18-pclos2.bfs.

The Control Centre - Browse and Configure Hardware identifies the dongle correctly as follows:

Identification
Vendor: ‎Cambridge Silicon Radio, Ltd
Description: ‎Bluetooth Dongle (HCI mode)
Media class: ‎Wireless|Radio Frequency|Bluetooth

Connection
Bus: ‎USB
Bus PCI #: ‎2
PCI device #: ‎3
Vendor ID: ‎0x0a12
Device ID: ‎0x0001

Misc
Module: ‎hci_usb

The KDE 'Configure Your Desktop' Bluetooth item reports:
"No Bluetooth adapters have been found"

Should the output of 'lsmod' list hci_usb somewhere?

Booting a live USB of the latest PCLOS does not bring the dongle to life. Booting a live USB of 'another popular distro' finds and activates the dongle thus proving the hardware.

Any suggestions, please, as to what I should try next?

Just17:
have a look at the dmesg output after inserting the dongle ......  there might be some indication there ....

zerocool:
The PCLOS team has recently updated many bluetooth and pulse audio files.
After these updates I lost my bluetooth connection to my headset (Motorola S10).
The first time I installed gnome bluetooh manager and that fixed the connection.
The next time, I had to uninstall pulse audio, reboot, reinstall pulse audio,
activate it in PCC, reboot, and everything works again...

Not very scientific (just guesses) but it worked.

Last few lines before inserting dongle

--- Quote ---wlan0: associated
ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready
usb 1-1.4: USB disconnect, device number 3
usbcore: registered new interface driver snd-usb-audio
wlan0: no IPv6 routers present

--- End quote ---

additional lines after inserting dongle

--- Quote ---usb 2-1.2: new full-speed USB device number 4 using ehci_hcd
usb 2-1.2: New USB device found, idVendor=0a12, idProduct=0001
usb 2-1.2: New USB device strings: Mfr=0, Product=0, SerialNumber=0

--- End quote ---

This is consistent with the Control Centre output after detecting the hardware.

Unless there are further ideas I may have to try zerocool's suggestion.

You can also try:
As su


--- Code: ---bluetoothd -u
--- End code ---

Reboot...
