USB Remote Control Enter Key Completely Blocked - No Events Fired (Need Help!)

Hi everyone,

I’m facing a critical issue with a custom USB remote control in my Tizen web app and could use a fresh set of eyes.

The Problem:

  • :white_check_mark: Samsung TV Remote Enter (keyCode 13): Works perfectly

  • :white_check_mark: Custom USB Remote (all other keys): Work fine, fire events correctly

  • :cross_mark: Custom USB Remote Enter: Completely blocked - zero events fired (no keydown, keypress, or keyup)

What’s Really Weird: USB Enter DOES activate focused UI elements (e.g., closes alert dialogs, activates buttons) but fires absolutely no capturable keyboard events.

Hardware Details:

  • Custom programmable USB TV remote (HID protocol, sends standard keyboard codes)

  • When tested on PC: All keys including Enter work perfectly and fire normal keyboard events

  • On Tizen TV: Every key works EXCEPT Enter

  • The remote sends keyCode 13 (standard Enter) - verified on PC

What I’ve Tried:

  • Event listeners on document, body, window (all phases - capture and bubble)

  • Hidden input elements to “trick” IME system

  • hwkey-event="enable" in config.xml (already set)

  • <tizen:metadata key="http://samsung.com/tv/metadata/use.ime" value="false"/>

  • <tizen:privilege name="http://tizen.org/privilege/tv.inputdevice"/>

  • Verified with on-screen debug output - other keys show up, Enter shows nothing

Test Code:

javascript

document.addEventListener('keydown', function(e) {
    console.log('Key:', e.keyCode); // Shows all keys except USB Enter
}, true);

My Setup:

  • Tizen web app with iframe loading external SPA

  • All standard USB remote keys work except Enter

  • Samsung documentation says Enter is mandatory and “detected automatically”

Has anyone encountered USB input devices where Enter specifically gets blocked? Is this a known Tizen limitation? Any workarounds?

Thanks in advance!
