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 [[Hardware|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]]. This same IRUSER service uses the New3DS HID hardware when running on New3DS(note that the main service for New3DS HID is ir:rst).

Note that the main service for New3DS HID is ir:rst, and these two service are mutually exclusive: when one is initialized and reading data from New3DS HID, the other cannot access it.
