[KARMIC] Bluetooth doesn't work (hci_cmd_task: hci0 command tx timeout) (Broadcom dongle)

Hi:

I can't transfer files or browse them through Bluetooth. On Ubuntu 9.04 it worked fine, but now with the new 9.10 (fresh install, not distro-upgrade) doesn't work anymore. I've read other posts with the same problem, but in previous versions, so apparently not everybody have this problem with Karmic and bluetooth.

Here are the technical info about this bug.

1) I connect my bluetooth dongle:

2) Querying bluetooth service status
$ sudo /etc/init.d/bluetooth status
 * bluetooth is running

3) Getting info about the bluetooth dongle
$ sudo hciconfig -a

4) Trying to scan devices
$ sudo hcitool scan

5) Now I repeat the tests but with bluetooth service down:
$ sudo /etc/init.d/bluetooth stop

6) Querying bluetooth service status:
$ sudo /etc/init.d/bluetooth status
 * bluetooth is not running

7) Querying hci status:
$ sudo hciconfig -a

8) Starting up the device:
$ sudo hciconfig hci0 up

9) Querying hci status again (more info is showed now):
$ sudo hciconfig -a

10) Trying to scan devices
$ sudo hcitool scan
Scanning ...

11) If I startup the bluetooth service again, then the history repeats again from step 2

MORE INFO:
The bluetooth icon that appears when I connect my dongle, don't save the value when I check the option "Make visible" (it's not grayed out, just don't save the value and disappears next time I open the bluetooth interface)
Scanning blutooth devices on the interface don't work either (obviously)

If there is any information you want, please tell me how to get it.

Thanks.
