USB2.0 HUB with full speed host and low speed device problem

I am using stm32f205 to do usb host which is able to use with hub.

I am able to do enumeration of hub and device over hub, however, during enumeration of device over hub, it shows lot of error. I use beagle usb 480 to monitor, and it shows invalid PID sequence. 

Do anyone know what is the reason of it and how to solve it? 

Below is the log of the error
