[Bug 289836] Re: Some bluetooth dongles don't work anymore

[Znupi]

okubax: what type of USB hardware do you have? What's the output of:
lsusb | grep Blue

(If you don't trust me about that command, here's what it does:
   - lsusb - lists all usb devices found on your system
   - grep Blue - takes that listing and only displays those entries that contain the word Blue)

** Description changed:

  This is a hardware support regression between Hardy and Intrepid
  
  == Regression details ==
  Discovered in version: Intrepid
  Last known good version: Hardy
  
  == Affected chips/dongles ==
  0a5c:200a Broadcom Corp. Bluetooth dongle
  2001:f111 D-Link Corp. [hex] DBT-122 Bluetooth adapter
  0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
+ 1131:1001 Integrated System Solution Corp. KY-BT100 Bluetooth Adapter
  
  == 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. Nothing.
  
  This is what's logged in daemon.log:

  lsusb lists the device as:
  
  Bus 002 Device 004: ID 0a5c:200a Broadcom Corp. 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.
