GUI getting slow once the CDC driver starts the transmission.

Hi,

STM32f429

The GUI getting slower once the the CDC driver starts the communication. If I go to the next page in the screen , the page loading very slowly. Even I am running the GUI task at high priority still it's happening. Once I remove the CDC sensor from the device , then the GUI works fastly. No delay when I Plug the USB stick in MSC class.

What could be the reason?

Thanks,

Param.
