Thank you for the reply Marvel.  I use the gnome bluetooth client which
apparently does manage bluetooth devices using bluetooth-input-service.
I  still have the problem of the devices disappearing if idle for too
long such as when i lock the desktop or log out for  a long period.
Sometimes I can re-enable the devices, but sometimes I cannot.  This is
frustrating.=20

I see a the following several times in the system log if i restart
bluetooth:
