Widget value change not sent to USB Host Port 2

Hi,

If I have a widget sending to Port 1, and a device connected to host device Port 1, when I change the widget, the host device receives the value.

However, if I have a widget sending to Port 2, and a device connected to host device Port 2, when I change the widget, the host device appears to not receive the value.

Is there some configuration I am missing or is this a bug?

Regards,

C.
