Custom HID Device on USBx stack on STM32

Hello,

Can someone, please, tell me where is a proper place to set a report size for an IN endpoint?

USBD_HID_EPIN_FS_MPS configured to any value above 9 causes suspension of the interface.

No matter what is written in the HID descriptor (and OUT reports are handled well), this value higher than 9 cases suspension. Whereas I need to send a reports with 55 bytes of data.
