@ohos.usbManager USB controlTransfer(控制传输)没有bmRequestType、bRequest相关对应

class PARA { 
  request: number = 0 
  reqType: usb.USBControlRequestType = 0 
  target: usb.USBRequestTargetType = 0 
  value: number = 0 
  index: number = 0 
  data: Uint8Array = new Uint8Array() 
} 
 
let param: PARA = { 
  request: 0, 
  reqType: 0, 
  target:0, 
  value: 0, 
  index: 0, 
  data: new Uint8Array() 
}; 
 
let devicesList: Array<usb.USBDevice> = usb.getDevices(); 
if (devicesList.length == 0) { 
  console.log(`device list is empty`); 
} 
 
usb.requestRight(devicesList[0].name); 
let devicepipe: usb.USBDevicePipe = usb.connectDevice(devicesList[0]); 
usb.controlTransfer(devicepipe, param).then((ret: number) => { 
  console.log(`controlTransfer = ${ret}`); 
})

let sendParam:PARA ={ 
  request:6, reqType:64, target:0, value:0, index:0 ,data:buffer1 
} 
 
let readParam:PARA ={ 
  request:6, reqType:192, target:0, value:0, index:0 ,data:buffer2 
}
