# Explore EP963x

## Introduction

The EP963x is a generic MCU used in many different products.

## 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:

* tw.com.exploretech.ep963x

## GUID Generation

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

* `USB\VID_17EF&PID_7226&REV_0001`
* `USB\VID_17EF&PID_7226`
* `USB\VID_17EF`

## Update Behavior

The device usually presents in runtime mode, but on detach re-enumerates with
the same USB PID in an unlocked mode. On attach the device again re-enumerates
back to the runtime locked mode.

## Vendor ID Security

The vendor ID is set from the USB vendor, in this instance set to `USB:0x17EF`

## External Interface Access

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