I recently updated my Netgear WNDR4300 to LEDE 17.01.4 and the only
thing that appears broken is the USB LED trigger. The LED works fine
and while the USB port is detected, functional, setting it as a
trigger does not make the LED blink. Was there any fix not backported
to the lede-17.01 branch?

I just tested my SmartRG SR400ac with 17.01.4 and it works fine.

root@LEDE:~# cat /sys/class/leds/bcm53xx\:green\:usb3/trigger
none nand-disk timer default-on netdev [usbport]

I also verified that plugging USB devices actually lights up the LED.

I see that ar71xx has an entry for WNDR4300:
ucidef_set_led_usbdev "usb" "USB" "netgear:green:usb" "1-1"
maybe it's not working for some reason?

After flashing the firmware, what's the output for
cat /sys/class/leds/netgear\:green\:usb/trigger
cat /sys/class/leds/netgear\:green\:usb/ports/*
