Realtek RTS54HID HID Support
|
|
=========================
|
|
|
|
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_0001`
|
|
* `USB\VID_0BDA&PID_1100`
|
|
* `USB\VID_0BDA`
|
|
|
|
Child I²C devices are created using the device number as a suffix, for instance:
|
|
|
|
* `USB\VID_0BDA&PID_1100&I2C_01`
|
|
|
|
Vendor ID Security
|
|
------------------
|
|
|
|
The vendor ID is set from the USB vendor, in this instance set to `USB:0x0BDA`
|
|
|
|

|

|
