Description

Add wake-up support for Turing 8.8" displays using the initial hardware revision.

My display reports the following serial device while the screen is sleeping:

  • VID: 1A86
  • PID: CA88
  • Serial number: CT88INCH

Opening this COM port wakes the display, after which the display exposes another serial device:

  • VID: 0525
  • PID: A4A7

This device is then detected as the active display COM port.

Problem

auto_detect_com_port() already handles USB7INCH and CT21INCH serial devices, but does not handle CT88INCH.

As a result, the wake-up procedure is not attempted when the 8.8" display is sleeping, and automatic COM port detection fails.

Fix

Add CT88INCH to the serial-number based wake-up detection.

Tested with hardware revision C and version 3.10.
