History
Richard Hughes bf72d393fd Split up FuUsbDevice into ->open() and ->setup() 
Before this change calling FuUsbDevice->open() opened the device, and
also unconditionally added various GUIDs and InstanceIDs which we
normally do in setup.
Then fu_device_setup() would call the FuSubclass->setup() vfunc which
would have no way of either opting out of the FuUsbDevice->setup()-like
behaviour, or controlling if the parent class ->setup is run before or
after the subclass setup.

Split up FuUsbDevice->open() into clear ->open() and ->setup() phases
and add the parent class calls where appropriate.

This means that ->setup() now behaves the same as all the other vfuncs.

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.
