create static method
Creates a UsbPort from vid, pid and optionally type and interface. throws an error on failure. This function will pop up a permission request if needed.
vid
= Vendor Id
pid
= Product Id
type
= One of UserSerial.CDC
, UsbSerial.CH34x, UsbSerial.CP210x, UsbSerial.FTDI, UsbSerial.PL2303 or empty for auto detect.
interface
= Interface of the Usb Interface, -1 for auto detect.
Example for a fake device with VID 0x1000 and PID 0x2000
UsbPort port = await UsbSerial.create(0x1000, 0x2000);
Implementation
static Future<UsbPort?> create(int vid, int pid, [String type = "", int interface = -1]) async {
String? methodChannelName = await _channel.invokeMethod("create", {"type": type, "vid": vid, "pid": pid, "deviceId": -1, "interface": interface});
if (methodChannelName == null) {
return null;
}
return new UsbPort(methodChannelName);
}
