SHIFT_L + COMMAND_L + certain keys blocked, Karabiner or hardware?

Hi! I have stumbled into a small problem that I can't figure out, and I thought somebody here might know what's going on :)

I have the following set up for my new mechanical USB keyboard (that seems to have 6 key rollover):

<?xml version="1.0"?>

<root>

   <item>

    <name>AULA keyboard fixes</name>

    <appendix>(fix backtick and cmd/opt keys for the AULA keyboard)</appendix>

    <identifier>private.backtick_aula_fix</identifier>

    <device_only>

      DeviceVendor::RawValue::0x1017,

      DeviceProduct::RawValue::0x0001

    </device_only>

    <!-- Backtick -->

    <autogen>__KeyToKey__ KeyCode::DANISH_LESS_THAN, KeyCode::DANISH_DOLLAR</autogen>

    <!-- Left side -->

    <autogen>__KeyToKey__ KeyCode::OPTION_L, KeyCode::COMMAND_L</autogen>

    <autogen>__KeyToKey__ KeyCode::COMMAND_L, KeyCode::OPTION_L</autogen>

    <!-- right side -->

    <autogen>__KeyToKey__ KeyCode::OPTION_R, KeyCode::COMMAND_R</autogen>

    <autogen>__KeyToKey__ KeyCode::COMMAND_R, KeyCode::OPTION_R</autogen>

  </item>

</root>

With this config, the EventViewer does not display events for when I press e.g. COMMAND_L+SHIFT_L+g COMMAND_L+SHIFT_L+b (remapped). However COMMAND_R+SHIFT_R+g and COMMAND_R+SHIFT_L+g are detected.

Is this because I have done something wrong in my private.xml or do you believe this might be because of hardware limitations?

Your XML works well on my machine.

Please confirm there are any outputs in the debug mode when you press
the g key while modifiers are pressed.

(If there is no output, it's hardware limitation.)

Thanks for the info, nothing shows up in the console, so I guess it’s a hardware limitation. Guess I'll have too look for a keyboard with full n key rollover.

Thanks for the work on Karabiner in any case, it makes my everyday life so much better!
