Introduction
This plugin can flash the firmware on the Synaptics Prometheus fingerprint readers.
Firmware Format
The daemon will decompress the cabinet archive and extract a firmware blob in an unspecified binary file format. The binary file has a vendor-specific header that is used when flashing the image.
This plugin supports the following protocol ID:
com.synaptics.prometheus
GUID Generation
These devices use the standard USB DeviceInstanceId values, e.g.
USB\VID_06CB&PID_00A9&REV_0001USB\VID_06CB&PID_00A9USB\VID_06CB&PID_00A9-cfgUSB\VID_06CB&PID_00A9&CFG1_3483&CFG2_500
Update Behavior
The device usually presents in runtime mode, but on detach re-enumerates with the same USB PID in an unlocked mode. On attach the device again re-enumerates back to the runtime locked mode.
Vendor ID Security
The vendor ID is set from the USB vendor, in this instance set to USB:0x06CB
External Interface Access
This plugin requires read/write access to /dev/bus/usb.
