KY-BT100 Bluetooth Adapter 044e:3001 Alps Electric Co., Ltd UGTZ4 Bluetooth Known workaround none (besides using Ubuntu Hardy) Description I upgraded from Hardy x64 to Intrepid x64 a few days back.

After upgrade bluetooth doesn't work. No icon in the tray, nothing. After restarting the bluetooth service with /etc/init. D/bluetooth restart the icon pops up, but it's a complete dud. Cannot set my computers bluetooth-name, can't pair devices, can't send or receive files.

This is what's logged in daemon.log: Oct 27 13:37:22 superbeast bluetoothd14641: Bluetooth daemon Oct 27 13:37:22 superbeast bluetoothd14641: Starting SDP server Oct 27 13:37:22 superbeast bluetoothd14641: Starting experimental netlink support Oct 27 13:37:22 superbeast bluetoothd14641: Failed to find Bluetooth netlink family Oct 27 13:37:22 superbeast bluetoothd14641: Can't init plugin /usr/lib/ bluetooth/ plugins/ netlink.

Bluetooth dongle How do I check if a driver is loaded for it? Lsmod grep blue gives me: bluetooth 70820 28 bnep,sco, rfcomm, l2cap,btusb but that doesn't change even if I yank the dongle from my computer. I have the latest updates to Intrepid applied. Same bug with another similar bluetooth dongle (I think it's the same chip): 2001:f111 D-Link Corp. hex DBT-122 Bluetooth adapter dmesg: 339.011026 hcicmdtask: hci0 command tx timeout daemon.log Oct 29 21:58:43 jernst-desktop bluetoothd6499: HCI dev 0 registered Oct 29 21:58:43 jernst-desktop bluetoothd6499: HCI dev 0 up Oct 29 21:58:48 jernst-desktop bluetoothd6499: Registered interface org.bluez.Service on path /org/bluez/hci0 Oct 29 21:58:53 jernst-desktop bluetoothd6499: Can't write class of device: Connection timed out (110) jernst@ jernst- desktop: $ sudo hcitool scan Scanning.

Ubuntu 8.10, bluez 4.12-0ubuntu5 I have a Bluetooth device that was functioning perfectly under 8.04 It is still there: # lsusb Bus 001 Device 005: ID 2001:f111 D-Link Corp.

Bluetooth icon appears, but I'm unable to change any preferences (visability, name) or connect any Bluetooth devices. In Ibex with kernel 2.6.24-19 Bluetooth works great, but my Nvidia won't work right so I'm stuck with non-working bt.

And it's not working for me too: Ubuntu 8.10 (upgraded from Hardy with blueman installed) I did uninstall blueman and reinstalled the 'standard' bluetooth packages My symptoms are a bit different: I can scan ans see other devices, but I can't pair any or transfer files.

BT seems to be working OK now to see and browse my mobile phone (I this reinstalling all the BT packages did the trick). I also managed to connect a BT headset without any problem. But my BT mouse still doesn't connect.

Even I I remove it from the paired list, when I rty to pair it, the computer telles me it is correctly paired, but the mouse stays in pairing mode. And If I want it to be working, i need to do: sudo hidd -search (when mouse still in pairing mode). No improvement with bluez 4.17 I added 'deb intrepid main' to my repositories and installed blueman. This seems to force the uninstallation of the buggy bluez 4 packages and install some bluez 3 packages instead. I had had error messages about obex. I installed also gnome-vfs-obexftp and obexftp.

I do not know if this is relevant. I has some problem with pairing.

I tried different ways with blueman and with wammu until it succeeded. As a result, I am unable to describe when and why it eventually succeeded.

(Pairing is very poorly documented.) Now my wammu connects to the phone automatically as with 8.04. I then uninstalled blueman because I was only interested in bluez 3, not really with blueman and it makes no difference to the connexion with wammu. Sorry that I had to drop bluez 4 but I really need to synchronize calendar and tasks from my phone with lightning in Thunderbird and I cannot wait for bluez 4.18, 4.19, 4.20. Bluetooth used to work on Ubuntu Hardy (8.04, 32-bit), and now fails on Ubuntu Intrepid (8.10, 32-bit).

Inquiry failed: Connection timed out user@COMPUTER:$ sudo hciconfig hci0 reset user@COMPUTER:$ sudo hcitool scan Scanning. My bluetooth also malfunctions. I managed to get it to pair with my phone once after emptying /var/lib/bluetooth/ however it wont do it again.

I'm not so sure mine is a kernel/driver problem as the phone does see the pc and my pc also sees the phone however i cannot pair or use file transfer/modem or HID capabilities.

Dominique, I have tried your suggestion and installed blueman (and bluez 3) however this did not fix anything for me. If anything it made things worse. Using blueman I could see my phone but not pair with it. My phone no longer saw the computer at all. The bluetooth-applet and bluetooth-wizard no longer did anything and didn't even recognize my bluetooth dongle was plugged in any more (eg.

When using bluez4 an icon would appear in my tray when i plugged my donge in. When using bluez3 this didnt happen any more.) Chris.
