Hi All, I am interfacing the K22FN512 with CP2102 in which K22 will act as a host and CP2102 as a USB device. I am able to enumerate the CP2102 but communication is not happening. I am using the MQX USB host CDC example. My prime target is to give CP2102

I am using MQX example of USB host CDC serial communication.

I am able to enumerate the CP2102 board and it is in resume state.

But I am not able to send command on it.

Like when I want to send the set descriptor command to it ( Interface descriptor) it is not giving me the same value when I do the get descriptor.

I am using K22FN512 on a FRDM board as USB host. Kindly support to get these two boards get communicated.

Thanks and Regards,

Jatin Vashisth
