0x00050000 | This writes an unknown u8 from IR-module state to index-word cmdreply[2]. |

This service was added with 8.0.0-18. Unlike the other IR services, this uses I2C deviceid 17(this deviceid isn't actually handled by the 8.0.0-18 I2C module). Therefore, this is probably for the new IR LED for the New 3DS.
IR Services
Only one session(two sessions starting with 8.0.0-18) to any of these services can be open at a time, thus only one/two process(es) can use any of these services at once. These services interface with hardware services gpio::IR and i2c::IR. The i2c::IR service is used for sending/receiving data.
IRU is for regular IR comms. IRUSER uses a custom IR protocol(above the physical layer). Both of these services use IrDA-SIR. The IR hardware seems to only support IrDA-SIR, other physical protocols such as the one for TV-remotes are not supported(going by the datasheet linked here for a different IC at least).
The protocol used with IRUSER involves encryption implemented in software. IRUSER is used for the Circle Pad Pro.
