Richard Hughes 52441f28a4 Allow objects to deserialize to XML 
This makes a lot more sense; we can parse a firmware and export the same XML
we would use in a .builder.xml file. This allows us to two two things:

 * Check we can round trip from XML -> binary -> XML

 * Using a .builder.xml file we can check ->write() is endian safe

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.
