The mm-detect service publishes device information to this object

HMI Media Player; any app


The mm-detect service uses this status object to notify the HMI of mediastore insertions and removals as well as synchronization events. During synchronization, mm-detect publishes device information in JSON format to the status object.

To listen for mediastore insertions and removals, mm-detect subscribes to objects in the /pps/qnx/mount/ directory.
