You might get some information from dmesg. dmesg lists
all the electronic devices your system knows about when it booted
up such as sound cards, disk controllers and network interfaces.
Your computer should make note of the bluetooth interface and
might even throw an error message if it doesn't like something
about it. The mouse should pair with the bluetooth system on
your computer and since your installation is an upgrade, this may
be an indication of trouble with the module associated with the
You can also see which modules your system loaded on boot
by using the command
At least this is true in a number of Linux versions. You don't
even have to be root.

Those were just some of the 81 modules that popped up on
the old Dell Dimension I am using, here.
Notice the psmouse module. You'll hopefully have something
comparable for the bluetooth mouse. It may not appear until you
try to pair your mouse with bluetooth.
Finally, there is a file in /etc called modules. Any
module whose name appears on a line in that file will be loaded
on boot. I used to have trouble on this system with sound from
the built-in sound chip set on the mother board. It would
usually be a no-show as sound card 0 and a usb sound card would
intermittently show up as card 0. By using /etc/modules to load
the sound module for the built-in card, it is always card 0.
Use that feature carefully since modules you don't
actually need just waste resources.
That should get you started with an afternoon of
head-scratching/banging as these things can be frustrating so
patience is a virtue.
