Overview

The /pps/services/multimedia/mtp/ directory stores objects containing information about attached MTP devices. Objects summarizing different devices are stored in different subdirectories. Each subdirectory has a name in this format:

PID-BusnoDevno

The name consists of the PID of the MTP driver started when the device was attached, followed by the bus number and device number. With each device attachment, the system starts another MTP driver process; if 5 MTP devices are attached, 5 drivers are launched. Within any of these driver subdirectories, you can find the devinfo object (which contains device-identifying and system software details) and a subdirectory with storage objects (which store the last modification time and other details for the storages on the device).
