USBX endpoint address error , UX_MAX_DEVICE_ENDPOINTS

[ABasi.2]

Hi!

with cube IDE i'm trying to develop a USB device with 3 classes using  a STM32H523 with USBX and threadX.

If i select USB HID,USB MSC and USB ACM (virtual com port) the code is succesfully generated but if i close and reopen the .ioc GUI i have this message error:

the value of UX_MAX_DEVICE_ENDPOINTS can't be less then number of endpoints used.(used endpoints: 7). it will be set to 6.

what does it mean? is not possible to have 3 classes? or i have to change something in the endpoints and it can be done?

there is an example like this? or a guide to understande the endspoint manage

thank you
