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`
|
|
|
|
