I guess, we can get rid of all these hacks and the search code, by
tagging the mouse device we need to find, with:
..., ENV{HID2HCI_SWITCH}="1", RUN+="hid2hci --methodfill --devpath=%p"

and for the bluetooth device we just let it trigger the
tagged mouse device when it goes away, with:
..., ENV{REMOVE_CMD}="/sbin/udevadm trigger --action=change --subsystem-match=usb --property-match=HID2HCI_SWITCH=1"

That way the disappearing bluetooth device would just cause
a "change" event at the mouse device, which would trigger
the original rule again.
It would not need any further search logic, and the resume case
would run the same rules as the plug-in case.
