I'm trying to migrate some code from old FLS USB to KSDK USB stack and I'm facing some troubles to find basic functions like _send and _recv when working with CDC class. The "USB Stack Device RM" on session and saws about "usb_device_cdc_acm_send" and "usb_device_cdc_acm_recv" respectively but I couldn't find those functions anywhere. Also the CDC_VCOM example doesn't make use of them to send and receive data to and from host, instead it writes or reads a buffer and makes use of "USB_DeviceSendRequest" function. Where can I find those _send and _recv functions pointed by documentation?
