Freescale USB stack 5.0 DTR issue

Greetings,

 

Quick question regarding the USB 5.0 in CDC mode.  When we use 5.0 USB CDC com stack with Kinetis KL25, the host PC has to set DTR flag in order to talk to KL25. But with Freescale 4.1 USB stack, DTR is not required to set.  We are not sure where exactly in the Freescale 5.0 USB stack we need to modify in order to resolve this DTR issue.

 

Has anyone run into this?  Khow why this may have changed and how to gor back to not require DTR on the host PC?

 

Regards,

-Dan
