[SO-101] USB port detection and serial permissions for educators schools (beginner)
SO-101 discussion on USB port detection, serial permissions, device naming, and first-setup issues that block bringup in classrooms and labs.
A very searchable SO-101 problem is also one of the most basic: the arm is connected, but the host machine does not see the right serial port or the user lacks permission to access it.
What are your first checks when SO-101 is not detected or serial access keeps failing during setup?
Please share operating-system gotchas, device naming issues, permission fixes, and anything that helps classrooms avoid repeated first-day setup friction.
If you reply, include one exact detection symptom and one exact check or command that solved it.
This thread will rank best if replies include the exact symptom, operating system, and fix rather than generic driver advice.
If you run SO-101 in shared classrooms, mention what you standardized so every student machine behaves the same way.
A one-minute first-setup checklist is welcome. That is the kind of answer people bookmark and reuse.
