Every SUPUSB/SUPUSBFLT CTL_CODE was computed with Access = 0 instead of FILE_WRITE_ACCESS (2 << 14), so the driver dispatch rejected each call with STATUS_INVALID_DEVICE_REQUEST and the export host could not even pass monitor GET_VERSION. Values now match usbipd-win's interop definitions (VBoxUsb.cs / VBoxUsbMon.cs).
