Richard Hughes 28678235cd Move the fuzzing files into the plugin directories 
We only had to pile everything into the src/fuzzing/firmware directory
because honggfuzz could not cope with more than one input path.

This way each plugin is self contained and easy to copy.
Also, install the fuzzing builder objects as this fixes the installed
tests when srcdir does not exist.

Based on a patch by Jan Tojnar <jtojnar@gmail.com>, many thanks.

Synaptics CAPE devices

Introduction

This plugin is used to update Synaptics CAPE based audio devices.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob.

This plugin supports the following protocol ID:

  • com.synaptics.cape

GUID Generation

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

  • USB\VID_1395&PID_0293

These devices also use custom GUID values, e.g.

  • SYNAPTICS_CAPE\CX31993
  • SYNAPTICS_CAPE\CX31988

Update Behavior

The firmware is deployed when the device is in normal runtime mode, and the device will reset when the new firmware has been written.

Vendor ID Security

The vendor ID is set from the USB vendor, in this instance set to USB:0x1395

Plugin-specific flags

  • use-in-report-interrupt: some devices will support IN_REPORT that allow host communicate with device over interrupt instead of control endpoint, since: 1.7.0

External Interface Access

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