我正在嘗試從通過 USB 連接到帶有usb4java庫(kù)的 Windows 10pro 機(jī)器的 RFID 閱讀器讀取消息。我已經(jīng)設(shè)法聲明了接口、打開了管道并為數(shù)據(jù)注冊(cè)了偵聽器，但是從未觸發(fā)過偵聽器。閱讀器充當(dāng)鍵盤，它讀取的任何內(nèi)容最終都會(huì)出現(xiàn)在活動(dòng)應(yīng)用程序中，例如我打開的 IDE，而不是在listener中。UsbInterface usbInterface = activeInteface(device);// there is only one endpoint in the listUsbEndpoint endpoint = (UsbEndpoint)usbInterface.getUsbEndpoints().get(0);UsbPipe pipe = endpoint.getUsbPipe();try {     usbInterface.claim();     // true     System.out.println("claimed usb interface: " + usbInterface.isClaimed());     pipe.open();     // true     System.out.println("pipe open: " + pipe.isOpen());     pipe.addUsbPipeListener(new MessageListener());     // true     System.out.println("pipe active: " + pipe.isActive());     // keep main thread alive, async call should be done from another thread i guess     Thread.sleep(15000);    }   catch (Exception any) {System.out.println(any);} }和聽眾：private static class MessageListener implements UsbPipeListener {    @Override    public void errorEventOccurred(UsbPipeErrorEvent event) {        System.out.println(event.toString() + " , " +event.getUsbException());    }    @Override    public void dataEventOccurred(UsbPipeDataEvent event) {        // this code block never triggers        System.out.println("listener ...);        int actualLength = event.getActualLength();        System.out.println("length: " + actualLength);        byte[] data = event.getData();        System.out.println("data length " + data.length);    }}我還在上面的塊中嘗試了同步讀取而不是異步讀取，如下所示：byte[] buffer = new data[8];// this fails on its own, don't even need to read something with RFID readerint received = pipe.syncSubmit(buffer);失?。篣SB error1: Transfer error on interrupt endpoint: Input/Output error有一些庫(kù)支持的特定于 Windows 的屬性：org.usb4java.javax.useUSBDK = true 但是當(dāng)我嘗試將它設(shè)置為異常時(shí)，這失敗了。我對(duì) USB 設(shè)備沒有任何經(jīng)驗(yàn)，所以不確定如何從這里開始。代碼有問題嗎，我需要 USBDK 還是設(shè)備不支持 libUSB 驅(qū)動(dòng)程序？遺憾的是，這不是我的設(shè)備，我無(wú)法訪問該設(shè)備的文檔，因此無(wú)法確定它是否是設(shè)備驅(qū)動(dòng)程序問題。
