Latency Joystick Data 

Hi,
I tried to use your foxglove extension for joystick. When I enable publish mode, I could not use foxglove. I can't send or get data instantly. But when I disable publish mode, I can get all data(scan, image..) instantly. when I tried with keyboard mode on, there is no latency, i guess the problem is using joystick extension with a physical joystick
Any support will be appreciated.
