Unable To Detect Swc For Fingerprint Driver

The error "unable to detect SWC" (Software Component) typically refers to a missing or improperly installed Software Component

Understanding the cause is half the battle. This error does not typically indicate a hardware failure (though we will test for that). The primary culprits fall into four categories: unable to detect swc for fingerprint driver

The Fingerprint Driver relies on the SWC (often a Trusted Execution Environment or Secure Enclave processor) to handle cryptographic operations and match-on-chip logic. Currently, if the SWC is unresponsive (due to firmware crash, I2C/SPI bus failure, or secure boot issues), the driver attempts to poll the device indefinitely or returns a generic "Device Not Found" error. This makes it impossible for the OS or end-user to distinguish between a disconnected sensor and a secure component failure.
