Member Description
bmRequestType
REQUEST_TYPE _USB_SETUP_PACKET::bmRequestType
This bit-mapped field identifies the characteristics of the specific request.
_BM_T.
bRequest
uint8_t _USB_SETUP_PACKET::bRequest
This field specifies the particular request. The Type bits in the bmRequestType field modify
the meaning of this field.
USBD_REQUEST.
wValue
WORD_BYTE _USB_SETUP_PACKET::wValue
