I believe the bluetooth part is working fine as I get two devices in /dev/input .  If I cat /dev/input/event5 I get a stream of characters when I press keys, and when  I cat /dev/input/event6 I get a stream of characters when I move the mouse.  I have the following in /etc/X11/xorg.conf.d/10-evdev.conf

There are no /etc/X11/*.conf  files, only the xorg.conf.d directory which contains the 10-evdev.conf above and a 10-quirks.conf (one entry to do with ThinkPad) and 20-nvidia.conf.

It looks like at least part of your problem would be solved if you made sure you were accessing the correct devices.  It is not going to be the case that the event devices get the same number on every boot.  This needs to be handled at the udev level by creating symlinks for the devices or some other stratagem that gives you a stable device name.  For example I have a keyboard that exposes two event devices, and I have these rules:

KERNEL=="event*", SUBSYSTEMS=="usb", ATTRS{bInterfaceClass}=="03", ATTRS{bInterfaceProtocol}=="01", ATTRS{bInterfaceNumber}=="00", SYMLINK+="input/event-kbd" ENV{WAYLAND_SEAT}="1" ENV{ID_INPUT}="1" ENV{ID_INPUT_KEY}="1"
KERNEL=="event*", SUBSYSTEMS=="usb", ATTRS{bInterfaceClass}=="03", ATTRS{bInterfaceProtocol}=="00", ATTRS{bInterfaceNumber}=="01", SYMLINK+="input/event-mm" ENV{WAYLAND_SEAT}="1" ENV{ID_INPUT}="1" ENV{ID_INPUT_KEY}="1"
KERNEL=="event*", SUBSYSTEMS=="usb", ATTRS{bInterfaceClass}=="03", ATTRS{bInterfaceProtocol}=="02", SYMLINK+="input/event-mouse" ENV{WAYLAND_SEAT}="1" ENV{ID_INPUT}="1" ENV{ID_INPUT_MOUSE}="1"

They have the result of ensuring that I can access event-kbd, event-mm, and event-mouse.  (You do not need the WAYLAND_SEAT part for using X.)  You then write your InputClass rules with respect to the stable device names, although I find that ID_INPUT and ID_INPUT_MOUSE give me what I need with no additional rules beyond the builtin InputClass selection.

The person who asked the other day about a keyboard that exposes two event devices would be well advised to do something similar to this and may then find that nothing in xorg.conf is needed.
