![]() It's actually quite hard to build a front-end for fwupd at the moment as you're never sure when the progress bar is going to zip back to 0% and start all over again. Some plugins go 0..100% for write, others go 0..100% for erase, then again for write, then *again* for verify. By creating a helper object we can easily split up the progress of the specific task, e.g. write_firmware(). We can encode at the plugin level "the erase takes 50% of the time, the write takes 40% and the read takes 10%". This means we can have a progressbar which goes up just once at a consistent speed. |

Fresco PD
Introduction
This plugin is used to update Power Devlivery devices by Fresco.
Firmware Format
The daemon will decompress the cabinet archive and extract a firmware blob in an unspecifed binary format.
This plugin supports the following protocol ID:
- com.frescologic.pd
GUID Generation
These devices use the standard USB DeviceInstanceId values, e.g.
USB\VID_1D5C&PID_7102&REV_0001
USB\VID_1D5C&PID_7102
USB\VID_1D5C
These devices also use custom GUID values, e.g.
USB\VID_1D5C&PID_7102&CID_01
Update Behavior
The firmware is deployed when the device is in normal runtime mode, and the device will reset when the new firmware has been written.
Vendor ID Security
The vendor ID is set from the USB vendor, in this instance set to USB:0x1D5C
External Interface Access
This plugin requires read/write access to /dev/bus/usb
