Bug description:
SRU justification:
Impact: A series of bluetooth dongles [1] do not work properly with the new
btusb driver which replaced usb_hci. This has been fixed upstream
(2.6.29-rc3). The required changes are all local to the btusb driver.
Fix: The following three patches are required to fix this (two as prerequisite
and one for the actual fix). The fix deviates from upstream by the change
of a version number and the missing resume part which does not exist for
Intrepid nor Jaunty.
Test: Fix has been tested by bug reporters.

Bluetooth doesn't work for at least the following devices:
ID 1131:1001 Integrated System Solution Corp. KY-BT100 Bluetooth Adapter
ID 1131:1004 Integrated System Solution Corp. Bluetooth Device
ID 2001:f111 D-Link Corp. [hex] DBT-122 Bluetooth adapter
ID 0a5c:200a Broadcom Corp. Bluetooth dongle
They don't work properly with the newer btusb driver, which replaced
hci_usb by default in 2.6.27. This hasn't been fixed upstream as of
v2.6.29-rc3.
Original message below:
Association with Bluetooth works using kernel 2.6.26, since the
updates to 2.6.27 (both -1 and -2) association fails. I can scan and
see bluetooth devices but not pair.
Using my phone, I start the association process, the phone asks for a
passkey, and in 2.6.26 the popup window appears normally allowing me
to enter the passkey. In 2.6.27 the dialog box never appears.
If I use hcitool:
:~$ sudo hcitool cc 00:1B:59:96:A6:DD
:~$ sudo hcitool auth 00:1B:59:96:A6:DD
HCI authentication request failed: Connection timed out
the dialog box appears very very briefly then vanishes.
dmesg shows a couple of problems:
[25791.306170] btusb_intr_complete: hci0 urb ffff88004dd0fb40 failed to
resubmit (19)
[25791.315446] btusb_send_frame: hci0 urb ffff880048542840 submission failed
and the syslog shows that there was an attempt to associate:
