Introduction
This plugin allows the user to update any supported hub and attached downstream ICs using a custom HID-based flashing protocol. It does not support any RTS54xx device using the HUB update protocol.
Other devices connected to the RTS54HIDxx 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 ID:
com.realtek.rts54
GUID Generation
These devices use the standard USB DeviceInstanceId values, e.g.
USB\VID_0BDA&PID_1100&REV_0001USB\VID_0BDA&PID_1100USB\VID_0BDA
Child I²C devices are created using the device number as a suffix, for instance:
USB\VID_0BDA&PID_1100&I2C_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:0x0BDA
