Description: Reference for FwupdPlugin-1.0: Plugin: Logitech Scribe

#### Plugin: Logitech Scribe

## Introduction

This plugin can upgrade the firmware on Logitech Video Collaboration products (Scribe), 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.scribe`

## GUID Generation

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

- `VIDEO4LINUX\VEN_046D&DEV_08E2`

## 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 access to `/dev/bus/usb`, `/dev/video0`. This plugin requires the `UVCIOC_CTRL_QUERY` ioctl interface.

## Version Considerations

This plugin has been available since fwupd version `1.8.8`.
