Mouse not reconnecting after Timeout

Hi,

My Logitech MX LASER does not reconnect after the idle timeout.
If i either pull the dongle and replug it or switch off the mouse and switch
it back on or do a

 dbus-send --system --type=method_call \
           --dest=org.bluez /org/bluez/hci0 \
           org.bluez.Adapter.DisconnectRemoteDevice \
           string:"00:07:61:3F:1B:6D"

then it reconnects fine.
This happens with all dongles (The internal one in my hp2510p, one of the CSR
based HAMA mini-dongles, ...)

I'm running 2.6.25.3 and bluez-{libs,utils}-3.31 with btusb (but it also
happened with hci_usb).
My DELL BT Keyboard and other mice are working fine and reconnecting after
timeout. I have reports of similar symptoms from apple bt-keyboard users.

I will attach a gzipped hcidump logfile obtained like that:

Wait until the timeout surely expired, then
- hcidump -X -V > /tmp/hcidump.out
- now move the mouse, nothing happens with my mouse cursor
- stop hcidump
- hcidump -X -V >> /tmp/hcidump.out
- move the mouse again
- disconnect the mouse with the above dbus-send command
- move it again, now it reconnects

I hope this helps to finally fix this old annoying bug ;-)

Thanks,

	Stefan
