I am also affected by this problem.

The fact is that the power management system monitors the battery level
of the bluetooth mouse, and this makes the appointment service to stop
working (or not having priority).

Perhaps a solution to the problem would be to disable/lock the module
responsible for monitoring the battery level of the mouse. But I do not
know if this is done by a power management module or by an Ubuntu
bluetooth stack plugin.

Could anyone answer this, please?

Thanks in advance.

Title:
  050d:0017 Bluetooth mouse randomly disconnects

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Since upgrading to Quantal, my Belkin bluetooth mouse disconnects
  sporadically from my computer. Sometimes this will happen several
  times a day, at other times it will stay connected for almost the
  entire day without a problem.

  After the connection is dropped, Bluetooth seems to become
  unresponsive. Generally unplugging and replugging the USB adapter is
  necessary to return it to a usable state.

  It was extremely reliable under Precise.
