# 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`.
