Richard Hughes 2d00cda464 Remove PLUGINBUILDDIR and use G_TEST_SRCDIR and G_TEST_BUILDDIR instead 
This allows us to override the location we load data files from, which
allows us to do more kinds of installed tests in the future.

Also, move the global data/tests content into the place that it is used
as it was getting impossible to manage.

DFU

Introduction

Device Firmware Update is a standard that allows USB devices to be easily and safely updated by any operating system.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in DFU or DfuSe file format.

This plugin supports the following protocol IDs:

  • org.usb.dfu
  • com.st.dfuse

GUID Generation

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

  • USB\VID_273F&PID_1003&REV_0001
  • USB\VID_273F&PID_1003
  • USB\VID_273F

Update Behavior

A DFU device usually presents in runtime mode (with optional DFU runtime), but on detach re-enumerates with an additional required DFU descriptor. On attach the device again re-enumerates back to the runtime mode.

For this reason the REPLUG_MATCH_GUID internal device flag is used so that the bootloader and runtime modes are treated as the same device.

Vendor ID Security

The vendor ID is set from the USB vendor, for example USB:0x0A12

Quirk Use

This plugin uses the following plugin-specific quirks:

DfuFlags

Optional quirks for a DFU device which doesn't follow the DFU 1.0 or 1.1 specification.

Since: 1.0.1

DfuForceVersion

Forces a specific DFU version for the hardware device. This is required if the device does not set, or sets incorrectly, items in the DFU functional descriptor.

Since: 1.0.1

DfuForceTimeout

Forces a specific device timeout, in ms.

Since: 1.4.0

DfuForceTransferSize

Forces a target transfer size, in bytes.

Since: 1.5.6

External Interface Access

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