title: Plugin: RTS54HUB
---

Introduction

This plugin allows the user to update any supported hub and attached downstream ICs using a custom HUB-based flashing protocol. It does not support any RTS54xx device using the HID update protocol.

Other devices connected to the RTS54xx using I2C will be supported soon.

Firmware Format

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

This plugin supports the following protocol IDs:

  • com.realtek.rts54
  • com.realtek.rts54.i2c

GUID Generation

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

  • USB\VID_0BDA&PID_5423

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:0x0BDA

External Interface Access

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

Version Considerations

This plugin has been available since fwupd version 1.2.0.
