# Jabra
|
|
|
|
## 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:
|
|
|
|
### 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`.
