KSDK 1.3 USB Descriptor for MSD and CDC

Hello,

 

I am trying to implement the USB classes for MSD and CDC with the TWR-K60D100m. I am using KSDK 1.3 and Processor Expert.

I used the fsl_usb_device_msd_class component of KSDK 1.3 which is working well. Because there is no class for cdc, I used the example for the TWR-K60 from Freescale (composite device msd_cdc) and took the cdc files.

MSD and CDC are both working but only separately.

 

Because the Towerboard is just my testing device, I would like to use Processor Expert, so that it is easier to implement on my custom device (which I currently dont' have). That's why I would like to know, how I can enable the CDC or composite class driver configuration in the fsl_usb_descriptors. The MSD class driver configuration is enabled because I added fsl_usb_device_msd_class. But for the other ones, I can't find the classes...

 

I guess the alternative would be to write the USB descriptor with the different interfaces by myself. But if you know how to do this with Processor Expert (and KSDK 1.3), it would be great, if you can help me.

 

Thank you!
