-/**
- * Scan the system for attached logic analyzers / devices.
- *
- * This will try to autodetect all supported logic analyzer devices:
- *
- * - Those attached via USB (can be reliably detected via USB VID/PID).
- *
- * - Those using a (real or virtual) serial port (detected by sending
- * device-specific commands to all OS-specific serial port devices such
- * as /dev/ttyS*, /dev/ttyUSB*, /dev/ttyACM*, and others).
- * The autodetection for this kind of devices can potentially be unreliable.
- *
- * Also, sending various bytes/commands to (all!) devices which happen to
- * be attached to the system via a (real or virtual) serial port can be
- * problematic. There is no way for libsigrok to know how unknown devices
- * react to the bytes libsigrok sends. Potentially they could lead to the
- * device getting into invalid/error states, losing/overwriting data, or...
- *
- * In addition to the detection, the devices that are found are also
- * initialized automatically. On some devices, this involves a firmware upload,
- * or other such measures.
- *
- * The order in which the system is scanned for devices is not specified. The
- * caller should not assume or rely on any specific order.
- *
- * After the system has been scanned for devices, the list of detected (and
- * supported) devices can be acquired via sr_device_list().
- *
- * TODO: Should return int.
- * TODO: Error checks?
- * TODO: Option to only scan for specific devices or device classes.
