Diagnose embedded USB enumeration, descriptors, CDC/REPL ports and intermittent disconnects. Use when requests involve a missing USB device, wrong interface, native USB versus serial bridge, endpoint failures or conflicting monitors.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
4 rules. About 0 are common, 4 are distinctive, and 0 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈4
Distinctive · estimate
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 9
Read the shared embedded contract and keep source/build, device and physical evidence separate.
- Distinctive: line 12
Read USB diagnosis. Identify connector, data-capable cable, power path, native USB controller versus UART bridge, VID/PID, interfaces, …
- Distinctive: line 28
Use the matching platform skill for USB stack configuration.

Do not erase firmware or reinstall arbitrary drivers to fix an unidentified transport symptom.
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

USB Debugging
Read the shared embedded contract and keep source/build, device and physical evidence separate.
Read USB diagnosis. Identify connector, data-capable cable, power path, native USB controller versus UART bridge, VID/PID, interfaces, serial identity and host OS. Record enumeration before and after the event; a changing port name is not necessarily a different physical board.
Separate no electrical connection, failed enumeration, missing driver/interface, port ownership and application protocol. Record descriptors, endpoint types, configuration and host logs with credentials/private serials redacted in public reports. Check D+/D- wiring, clock/PHY/VBUS expectations and power externally only against the exact board design.
Close conflicting serial monitors before a selected REPL/debug session. MicroPython raw REPL and auto-reset tools can change runtime state. Native USB may disappear during reset, breakpoint halt or firmware reconfiguration; a UART bridge can remain enumerated while the MCU is stopped.
Use the matching platform skill for USB stack configuration. Deliver the layer where evidence stops, a reproducible host check and the next targeted test. Do not erase firmware or reinstall arbitrary drivers to fix an unidentified transport symptom.
See platform coverage for the exact tested combination. A source procedure is not a claim that every target was tested.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
