I have the Microsoft Desktop Elite for Bluetooth keyboard/mice combo
(described
athttp://www.microsoft.com/hardware/mouseandkeyboard/productdetails.aspx?pid=033).
I dot have the original Microsoft USB dongle, I use one that describe
itself as "Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)".

I have HIDD_ENABLED=1 in /etc/default/bluetooth, and I have added "--
connect xx:xx:..." for both the kb and mouse MAC address in
HIDD_OPTIONS.

After a cold boot, with the dongle plugged in, device do not work.  If I
get to the shell and do "sudo hidd --search", device are not detected
and do not work.  If I push the "Make/Break Connection" button on the
keyboard and mice and do "sudo hidd --search" again, bith device are
detected and become functionnal.

If I do not use either device for about 10 minutes, they stop being
usable.  In this state, they act like after a cold boot; just doing
"sudo hidd --search" is not enough, I have to press the "Make/Break
Connection" then do "sudo hidd --search" to make them work again.

In Microsoft Windows XP SP2, device are working on cold boot without
using the devices "Make/Break Connection" and remain usable even when
unused for a long period of time.

My assumption is that this behavior is specific to this pair of device
(hardware-related), but I have no other Bluetooth HID device to confirm
or infirm that assumption.  If ever get my hands on one, I will confirm
either way.

I will bring the mouse with me this week, so if you want me to test
anything else, I should be able to do so in short order.
