[Bug 1900935] Re: Support to upgrade Synaptic fingerprint firmware from LVFS

[Mario Limonciello]

** Description changed:

- There are some information provided from Synaptics
- --
- MFW-RC15E has been uploaded to LVFS as test mode, but we need fwupd v1.4.6 to support our iota update.
- ---
+ [Impact]
  
- Here is the v1.4.6
- https://github.com/fwupd/fwupd/releases/tag/1.4.6
+ Versions of fwupd older than 1.4.6 can not support upgrading Synaptics
+ fingerprint readers.
  
- Need to backport related patches to support it.
+ 
+ [Test Case]
+ Try to update firmware from a synaptics fingerprint reader.
+ 
+ [Regression Potential]
+ This will require moving to fwupd 1.4.6 which is newer than the release in focal.  The patches for Synaptics fingerprint reader support depend upon daemon code that is not present in the 1.3.x series.
+ 
+ There may be potentially other bugs with moving to this release.  More
+ devices are supported which might mean exercising extra code paths.
