How do I make my USB Bluetooth dongle work in Ubuntu 11.04 ? (Can't init device hci0: Connection timed out (110)) [closed]
- by MaikoID
I've a USB bluetooth dongle
root@maiko-cce-lin:~# lsusb | grep Bluetooth
Bus 001 Device 007: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
that isn't working properly, hardly-ever it works but stops working in my next reboot.
what I've tried
it isn't software blocked
root@maiko-cce-lin:~# rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
1: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
my device is recognized by hciconfig
root@maiko-cce-lin:~# hciconfig -a

but I can't turn on my hci interface

I don't understand why.. the hcitool command doesn't show any device.
root@maiko-cce-lin:~# hcitool dev

I've tried to restart my bluetooth service too with this command and make all these previous commands again but without success.
root@maiko-cce-lin:~# service bluetooth restart
* Stopping bluetooth [ OK ]
* Starting bluetooth [ OK ]
root@maiko-cce-lin:~#
The dongle works if you disconnect it from usb, wait a few seconds and connect it again. so there must be better solution for it ( a solution not involving physically removing the dongle!)
