USB 4.0.3 CDC HOST doesn't receive data

I modified the example from "...\Freescale USB Stack v4.0.3\Source\Host\examples\cdc_serial\cw10\kinetis_l2k" to use it with openSDA on FRDM-KL25Z.

I can send data from Host to CDC device but not from Device to HOST. It doesn't works. Host doesn't receive nothing.

Function  _io_cdc_serial_read always return 0.

If I connect the device to a PC,  I can see in the hyperterminal the data sent, so the problem seems to be on the host.

 

 

I need change any specific register initialization code?

This example works correctly in TWRMKL25z ?
