Only one session to either of these services can be open at a time, thus only one process can use either 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), which is for 3DS<>3DS comms(?). The IR hardware operates in the IrDA modulation mode by default, IRU doesn't have an interface for using other modes(such as the one for TV-remotes) via hardware.
