Richard Hughes faa7871b08 Remove duplicate ->probe() calls to speed up startup by 150ms 
Now incorporate is fixed to copy across the properties we need in the
superclass, we don't need to do the subclass ->probe().

Note, we still need to do the subclassed ->probe() when using
FU_UDEV_DEVICE_FLAG_VENDOR_FROM_PARENT or when looking at properties
on the parent device.

This also removes the spurious 'already set GType to FuVliUsbhubDevice,
ignoring FuVliUsbhubDevice' messages when running the daemon.

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
  • USB\VID_050D&PID_008B
  • USB\VID_047D&PID_80C8
  • USB\VID_0502&PID_04C4

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
  • USB:0x050D
  • USB:0x047D
  • USB:0x0502

External Interface Access

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