If I connect the Oculus Rift S to the PC, Qt sees it as a QTouchDevice::TouchScreen.

If I run this code:

auto tdevs = QTouchDevice::devices();
for (const auto* td : tdevs)
{
   if (td->type() == QTouchDevice::TouchScreen)
   {
     qDebug() << td->name() << td->maximumTouchPoints() << td->capabilities();
       }

}

I get this output:

"" 9 QFlags<QTouchDevice::CapabilityFlag>(Position|Area|NormalizedPosition|MouseEmulation)

No touch screen is connected to the PC. If I disconnect the Oculus Rift, I get no output.
