Non-Blocking USB CDC Read and Write and non Blocking plug and unplug USB

Hello

I have considered the attached example I found in the following forum https://en-support.renesas.com/knowledgeBase/18870541,

The example works well.
However, if you disconnect and reconnect the USB cable, the callbacks stop working and cannot be reset

 tried to redo the initialization but the function ux_device_class_cdc_acm_ioctl with UX_SLAVE_CLASS_CDC_ACM_IOCTL_TRANSMISSION_START return 0x18, i tried to initialize the usb but the result doesn't change

how can I reset everything correctly?

/* Specify the read and write callback functions that can be used with the ux_device_class_cdc_acm_ioctl function */
call_back.ux_device_class_cdc_acm_parameter_read_callback = cdc_acm_read_callback;
call_back.ux_device_class_cdc_acm_parameter_write_callback = cdc_acm_write_callback;
status = ux_device_class_cdc_acm_ioctl(gp_cdc, UX_SLAVE_CLASS_CDC_ACM_IOCTL_TRANSMISSION_START, &call_back);

the return value the second time is 0x18
