Richard Hughes 40cd18fa97 Allow using a per-device global percentage completion 
It's actually quite hard to build a front-end for fwupd at the moment
as you're never sure when the progress bar is going to zip back to 0%
and start all over again. Some plugins go 0..100% for write, others
go 0..100% for erase, then again for write, then *again* for verify.

By creating a helper object we can easily split up the progress of the
specific task, e.g. write_firmware().

We can encode at the plugin level "the erase takes 50% of the time, the
write takes 40% and the read takes 10%". This means we can have a
progressbar which goes up just once at a consistent speed.

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.
