HCD_HandleTypeDef has 15 channels

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)

#hcd_handletypedef #hcd_hctypedef
