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.
GUID Generation
These devices use the standard USB DeviceInstanceId values, e.g.
USB\VID_273F&PID_1003&REV_0001USB\VID_273F&PID_1003USB\VID_273F
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 |
DfuJabraDetach |
Assigns the two magic bytes sent to the Jabra hardware when the device is in runtime mode to make it switch into DFU mode. | 1.0.1 |
