UsbSetupPacket Struct Reference

Backend-agnostic mirror of the standard 8-byte USB SETUP packet (TinyUSB's tusb_control_request_t). Identical wire layout on any USB stack. The bmRequestType bitfields (USB 2.0 spec Table 9-2) are exposed as accessor methods instead of a bitfield union, so call sites read almost the same as before: p_request->bmRequestType_bit.type -> p_request.type().
