History
Richard Hughes bf72d393fd Split up FuUsbDevice into ->open() and ->setup() 
Before this change calling FuUsbDevice->open() opened the device, and
also unconditionally added various GUIDs and InstanceIDs which we
normally do in setup.
Then fu_device_setup() would call the FuSubclass->setup() vfunc which
would have no way of either opting out of the FuUsbDevice->setup()-like
behaviour, or controlling if the parent class ->setup is run before or
after the subclass setup.

Split up FuUsbDevice->open() into clear ->open() and ->setup() phases
and add the parent class calls where appropriate.

This means that ->setup() now behaves the same as all the other vfuncs.

Fresco PD Support

Introduction

This plugin is used to update Power Devlivery devices by Fresco.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in an unspecifed binary format.

This plugin supports the following protocol ID:

  • com.frescologic.pd

GUID Generation

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

  • USB\VID_1D5C&PID_7102&REV_0001
  • USB\VID_1D5C&PID_7102
  • USB\VID_1D5C

These devices also use custom GUID values, e.g.

  • USB\VID_1D5C&PID_7102&CID_01

Update Behavior

The firmware is deployed when the device is in normal runtime mode, and the device will reset when the new firmware has been written.

Vendor ID Security

The vendor ID is set from the USB vendor, in this instance set to USB:0x1D5C

External interface access

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