#### Plugin: Jabra

## Introduction

This plugin is used to detach Jabra Speak Gen 1 devices to DFU mode.

## GUID Generation

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

- `USB\VID_0B0E&PID_0412`

## Quirk Use

This plugin uses the following plugin-specific quirks:

### JabraMagic

Two magic bytes sent to detach into DFU mode.

Since: 1.3.3

## Update Behavior

The device usually presents in runtime mode, but on detach re-enumerates with a different USB VID and PID in DFU APP mode. The device is then further detached by the `dfu` plugin.

On DFU attach the device again re-enumerates back to the Jabra runtime mode.

For this reason the `REPLUG_MATCH_GUID` internal device flag is used so that the bootloader and runtime modes are treated as the same device.

## Vendor ID Security

The vendor ID is set from the USB vendor, in this instance set to `USB:0x0A12`

## External Interface Access

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

## Version Considerations

This plugin has been available since fwupd version `1.3.3`.
