title: Plugin: Logitech Bulk Controller — Video Collaboration
|
|
---
|
|
|
|
## Introduction
|
|
|
|
This plugin can upgrade the firmware on Logitech Video Collaboration products
|
|
(Rally Bar and RallyBar 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`.
