Setup packet for control transfers.
uint8_t libusb_control_setup::bmRequestType |
Request type.
Bits 0:4 determine recipient, see libusb_request_recipient. Bits 5:6 determine type, see libusb_request_type. Bit 7 determines data transfer direction, see libusb_endpoint_direction.
uint8_t libusb_control_setup::bRequest |
Request.
If the type bits of bmRequestType are equal to LIBUSB_REQUEST_TYPE_STANDARD then this field refers to libusb_standard_request. For other cases, use of this field is application-specific.
uint16_t libusb_control_setup::wValue |
Value.
Varies according to request
uint16_t libusb_control_setup::wIndex |
Index.
Varies according to request, typically used to pass an index or offset
