Overview

When USB sticks are connected to the system, PPS objects appear under the /pps/qnx/device/ directory to expose hardware connectivity details. For USB devices, object names are of the form:

usb-bus_number.device_number

Note: If usblauncher is called with the -S option, the object name also includes the stack_number attribute before the bus_number (e.g., usb-0.0.3).

Here's a sample object:

[n]@usb-0.0.3
