Richard Hughes 87a8091bed trivial: Fix a crash using fu_firmware_image_get_chunks() 
Add a GError as it can return NULL for invalid circumstances. It's okay to
change the API as this symbol has not yet been in a tarball release.

DFU Support

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

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:

Quirk Description Minimum fwupd version
DfuFlags Optional quirks for a DFU device which doesn't follow the DFU 1.0 or 1.1 specification 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. 1.0.1
DfuForceTimeout Forces a specific device timeout, in ms 1.4.0
DfuForceTransferSize Forces a target transfer size, in bytes 1.5.6

External interface access

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