MTP event on Windows undetected (MTP_EVENT_XXX)

[Tiarkhog]

Hello. I’m using tinyUsb for a MTP stack embedded in a stm32L4.
I’m facing an issue : Windows doesn’t reload the files nor call MTP_OP_GET_OBJECT_HANDLES or MTP_OP_GET_OBJECT_INFO. I’m wondering how should I do.
I guess I have to use tud_mtp_event_send, isn’t it ? How do I can get the session_id (which seems to be 0 all the time) and the transaction_id ? What parameters should be set or how should this function must be used ?
The stm32 is writing some files, and I want is windows to download the whole file and not just what it kept in cache. I also would like windows to detect a new file if the stm32 create a new one

In tusb_config.h, it seems that only MTP_EVENT_OBJECT_ADDED is set. I added the other anyway.

Thanks in advance. Have a good day.
Thanks for this tinyusb stack.
