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.
