Richard Hughes d99f86023f trivial: Add getters to FuChunk 
At the moment FuChunks are sometimes mutable, and sometimes immutable, and it's
all a bit too low level for comfort.

Before we can do any kind of optimisation or verification we need plugins to
stop reading directly from the C structure. The aim here is to make FuChunk
optionally mutable without making assumptions about the memory model, and also
to be able to introspect it for the docs.

ColorHug Support

Introduction

The ColorHug is an affordable open source display colorimeter built by Hughski Limited. The USB device allows you to calibrate your screen for accurate color matching.

ColorHug versions 1 and 2 support a custom HID-based flashing protocol, but version 3 (ColorHug+) has now switched to DFU.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in a packed binary file format.

This plugin supports the following protocol ID:

  • com.hughski.colorhug

GUID Generation

These devices use the standard USB DeviceInstanceId values, e.g.

  • USB\VID_273F&PID_1001&REV_0001
  • USB\VID_273F&PID_1001
  • USB\VID_273F

Vendor ID Security

The vendor ID is set from the USB vendor, in this instance set to USB:0x273F

External interface access

This plugin requires read/write access to /dev/bus/usb.
