History
Richard Hughes 40cd18fa97 Allow using a per-device global percentage completion 
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.

Logitech Video Collaboration

Introduction

This plugin can upgrade the firmware on Logitech Video Collaboration products (Rally Bar and Rally Bar Mini), using USB bulk transfer.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in a packed binary file format.

This plugin supports the following protocol ID:

  • com.logitech.vc.proto

GUID Generation

These devices use the standard USB DeviceInstanceId values, e.g.

  • USB\VID_046D&PID_089B
  • USB\VID_046D&PID_08D3

Quirk Use

This plugin uses the following plugin-specific quirks:

Update Behavior

The peripheral firmware is deployed when the device is in normal runtime mode, and the device will reset when the new firmware has been written.

Design Notes

Vendor ID Security

The vendor ID is set from the USB vendor, in this instance set to USB:0x046D

External Interface Access

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