[Bug 268502] Re: Bluetooth doesn't work (hci_cmd_task: hci0 command tx timeout)

[Øyvind Stegard]

Confirming problems in current Jaunty Release Candidate with USB
Bluetooth dongle that comes with the Logitech DiNovo Edge keyboard. It
will initially work in HCI mode (i.e. pairing with keyboard works), but
if left idle, the dongle will suddenly revert to HID-mode, and I lose
the Bluetooth device.

Here's what appears in the kernel log when the dongle suddenly reverts itself to HID-mode:

I can run:
$ sudo hid2hci

and the Bluetooth device comes back and works OK paired with the
keyboard. Something is timing out somewhere. I would like the dongle to
always stay in HCI mode.

This problem did not happen in Ubuntu Intrepid.
