lsusb shows us that—sure enough—Apple's IR receiver is being loaded on boot:
# lsusb Bus 005 Device 002: ID 05ac:8242 Apple, Inc. Built-in IR Receiver
lsmod reveals hid_appleir is the module being loading for our remote. Let's blacklist it:
# echo 'blacklist hid_appleir' > /etc/modprobe.d/hid_appleir.conf # depmod -ae # update-initramfs -u # reboot now
That should take care of it!
