# Analogix
## Introduction
This plugin can flash the firmware of some Analogix billboard devices.
## Firmware Format
The daemon will decompress the cabinet archive and extract a firmware blob in
a Intel Hex file format. The resulting binary image is either:
* `OCM` section only
* `CUSTOM` section only
* Multiple sections excluded `CUSTOM` -- at fixed offsets and sizes
This plugin supports the following protocol ID:
* com.analogix.bb
## GUID Generation
These devices use the standard USB DeviceInstanceId values, e.g.
* `USB\VID_1F29&PID_7518`
## Update Behavior
The device is updated at runtime using USB control transfers.
## Vendor ID Security
The vendor ID is set from the USB vendor. The list of USB VIDs used is:
* `USB:0x1F29`
## External Interface Access
This plugin requires read/write access to `/dev/bus/usb`.
