If you have ever built an autonomous mobile robot, you have likely run into the dreaded "Shuffled USB Port" problem.
You boot up your robot, fire up your ROS 2 launch files, and... crash. Your LiDAR driver is trying to parse data from your IMU, and your IMU node is screaming about invalid serial frames. Because Linux assigns virtual serial paths like /dev/ttyUSB0 and /dev/ttyUSB1 based purely on which device initialized milliseconds faster, relying on default OS paths is a recipe for system instability.
When you are scaling up to dozens of Jetson Orin nodes—each equipped with an RPLIDAR C1 and a Yahboom 10-axis IMU—manually hardcoding paths or writing rigid scripts on every individual machine isn't viable.
Here is how production-grade robotics fleets handle plug-and-play USB binding dynamically using configuration-driven udev rules.
The Core Concept: Vendor ID vs. Physical Port vs. Serials
