Jabra Support

Introduction

This plugin is used to detach the Jabra device 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:

Quirk	Description	fwupd version
`JabraMagic`	Two magic bytes sent to detach into DFU mode.	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.
