I a wondering if it is possible to setup the host without VBUS and ID pin assigned. I would like to use USB A type (like laptops have) socket - there is no ID pin available and I do not VBUS detection as it is always ON.

Thanks @Community member , I confirm it is possible to configure USB host on L476 & L496 without any additional pins required (ID & VBUSx2).I tested it on Nucleo-L476RG and L496-Disco with very little extra added(just in USB_host.c) to automatically...
