Hi! I'm trying to use turing-smart-screen-python with a case built-in display (Pichau Ikaros).

Display connection:

  • Not HDMI/monitor mode. It is USB-only and shows up as USB Serial Device (COM3).
  • AIDA64 identifies it as: "USB Composite Device (CherryUSB CDC DEMO)" and "USB Serial Device (COM3)".
  • Hardware IDs: USB\VID_33C3&PID_7788&REV_0100 (and/or USB\VID_33C3&PID_7788)

Panel resolution (from the vendor software / HT_MONITOR):

  • 462 x 1920 (portrait)

What works:

  • Official vendor app (HT_MONITOR / HT_software) can drive the screen and show CPU/RAM/etc.

What does not work:

  • turing-smart-screen-python debug build connects to COM3 but loops with:
    "Display returned invalid or unsupported ID"
    "Display returned invalid or unsupported ID length"

Environment:

  • Windows 11
  • COM port: COM3
  • Intel Arc GPU (temps are fine in Windows Task Manager and other tools; unrelated to the screen detection)

Request:

  • Is this device supported / can support be added?
  • If you need logs, please tell me which debug output / command-line flags to enable to print the raw display ID bytes.
