The original code was written by Dell for the dell-dock plugin, but it's exactly the same code and NVM format for Intel reference hardware.

# Intel USB4
|
|
|
|
## Introduction
|
|
|
|
This plugin supports the Goshen Ridge hardware which is a USB-4 controller from Intel.
|
|
These devices can updated using multiple interfaces, but this plugin only uses the XHCI interface.
|
|
|
|
## Firmware Format
|
|
|
|
The daemon will decompress the cabinet archive and extract a firmware blob in
|
|
an unspecified binary file format, with vendor specific header.
|
|
|
|
This plugin supports the following protocol ID:
|
|
|
|
* com.intel.thunderbolt
|
|
|
|
## GUID Generation
|
|
|
|
These devices use a custom generation scheme, which is quite intentionally identical to thunderbolt
|
|
plugin:
|
|
|
|
* `TBT-{nvm_vendor_id}{nvm_product_id}`
|
|
|
|
## Update Behavior
|
|
|
|
By default the USB4 controller will reboot at the end of the update.
|
|
|
|
Some devices (e.g. inside some Dell docks) will instead be updated the next time the USB-C plug
|
|
from the dock is unplugged from the host, or when activated manually.
|
|
|
|
## Vendor ID Security
|
|
|
|
The vendor ID is set from the USB vendor, in this instance set to `USB:0x8087`
|
|
|
|
## External Interface Access
|
|
|
|
This plugin requires read/write access to `/dev/bus/usb`.
