Virtual COM Port Driver - is Overlapped IO Mode Supported ?

We are reading NMEA 0183 data from the USB port of our STM32 based product and our Windows PC Application has been written to use Overlapped IO to minimise performance issues when reading data from lots of COM ports.

The STM32 Virtual COM Port Driver returns an error code when we try to read data using the Overlapped IO functions in Windows, which makes us think that this mode is not supported in the driver. Can anyone confirm if this is true or better still can anyone confirm if they have managed to get the STM32 driver to work in Overlapped IO mode ?
