Latency measured: ~180ms for capture + transfer on USB 2.0. For a deep paper, these CVEs are relevant:

| IOCTL | Function | |-------|----------| | 0x222000 | Capture iris image (returns raw 8-bit grayscale) | | 0x222004 | Set LED brightness (parameter: 0-255) | | 0x222008 | Get device firmware version | | 0x22200C | Start video stream for focus assist | | 0x222010 | Stop video stream |

Modern Alternatives & Migration Path Given the obsolescence, a deep paper should conclude with pragmatic advice:
