I use a udev rule for this. I created a file in /etc/udev/rules.d
called remote-control-lirc.rules and put this line in it:

  SUBSYSTEM=="rc", ATTRS{protocols}=="*lirc*" RUN+="/bin/sh -c 'echo lirc > /sys$env{DEVPATH}/protocols'"

After creating that file, test the rule by running:

  $ udevadm test /devices/pci0000:00/0000:00:06.0/usb4/4-5/4-5:1.0/rc/rc2

(replacing that path with whatever the link in /sys/class/rc points to
currently). You should see a line at the end of the output saying it's
going to run the echo lirc command.

Later, when you reboot or disconnect/reconnect the receiver, the udev
rule should detect the new location of the receiver and echo lirc to
the appropriate file.
