Compiling examples/peripherals/usb/host/cdc

[EG1966]

Hi


I am trying to compile:
esp-idf/examples/peripherals/usb/host/cdc/cdc_acm_host/main/usb_cdc_example_main.c

which uses the file
"usb/cdc_acm_host.h"
but I cannot find this file.


I also want to compile:
esp-idf/examples/peripherals/usb/host/cdc/cdc_acm_vcp/main/cdc_acm_vcp_example_main.cpp

which uses the files
#include "usb/cdc_acm_host.h"
#include "usb/vcp_ch34x.hpp"
#include "usb/vcp_cp210x.hpp"
#include "usb/vcp_ftdi.hpp"
#include "usb/vcp.hpp"
but I cannot find these files.

Where can I find these files? thanks
