I tried this with the rc1 device as a test. I get this odd result:
# cat protocols
nec
# echo '+nec' > protocols
bash: echo: write error: Invalid argument
and ir-keytable still shows no protocols enabled
# ir-keytable
Found /sys/class/rc/rc0/ (/dev/input/event5) with:
Driver imon, table rc-imon-mce
Supported protocols: rc-6
Enabled protocols: rc-6

bus: 3, vendor/product: 15c2:ffdc, version: 0x0000

Found /sys/class/rc/rc1/ (/dev/input/event16) with:

I messed around some more with ir-keytable and got more segfaults
if I try to use the -d argument.
# ir-keytable -d /dev/input/event16 -p NEC -p RC6 -w
/lib/udev/rc_keymaps/rc6_mce
Read rc6_mce table
Wrote 63 keycode(s) to driver
Segmentation fault (core dumped)
-s at least doesn't segfault, but doesn't advance the cause.
# ir-keytable -s rc1 -p NEC -p RC6 -w /lib/udev/rc_keymaps/rc6_mce
Read rc6_mce table
Wrote 63 keycode(s) to driver
/sys/class/rc/rc1//protocols: Invalid argument
Couldn't change the IR protocols
# ir-keytable -s rc1 -p NEC -w /lib/udev/rc_keymaps/winfast
Read winfast table
Wrote 56 keycode(s) to driver
/sys/class/rc/rc1//protocols: Invalid argument
Couldn't change the IR protocols
