"Unable to detect SWC" is usually an enumeration/communication failure between host and fingerprint controller caused by hardware, power, firmware, driver, or OS configuration issues. A methodical, data-driven workflow—covering physical checks, bus enumeration, firmware loading, kernel binding, power domains, and secure-world constraints—quickly isolates the root cause. Upstream fixes in firmware, kernel, and ACPI/DT, plus improved QA and vendor tooling, eliminate most occurrences. | State | UI Text | Action |
