On STM32F7, the HS interface has 16 host channels.
But in the HAL, the HCD_HCTypeDef structure has only 15 HCD_HCTypeDef items.
Is this normal ?
Is this a bug ?
Is there an hidden reason ?
(I have an application which can have the need on the 16 channels because several devices will be connected via a hub)
