History
Richard Hughes b3f9841924 Support more than one protocol for a given device 
Devices may want to support more than one protocol, and for some devices
(e.g. Unifying peripherals stuck in bootloader mode) you might not even be able
to query for the correct protocol anyway.

Synaptics Prometheus

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_0001
  • USB\VID_06CB&PID_00A9
  • USB\VID_06CB&PID_00A9-cfg
  • USB\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.
