External monitor with touch screen not working on 2S with Android 11

[Al Avitr 0]

Hello! Exciting to be using the Tinker Board 2S! My application requires Android 11 with an external touch screen display. The issue I am facing is that the touch screen input to Tinker board 2S via the USB does not work. Touch input is not detected. The same setup works fine on a Blackberry Pi 4 running Emteria Android. So, I have concluded that it must be some issue/setting on the Android 11 running on the Tinker Board 2S.

FYI, a wireless mouse/keyboard work just fine on 2S.

Anyone with experience using an external touch screen monitor via USB?

Thanks!
