ByteBuffer byteBuffer = ByteBuffer.allocate(9);;    
UsbRequest request = new UsbRequest();
request.initialize(mConnection,mEndpointIntr);
boolean b = request.queue(byteBuffer, 9);
Log.d(TAG, "start the request wait");
UsbRequest ur = mConnection.requestWait();

我想使用Android USB中断.上面的代码是一个从我自己的USB板接收数据的线程.但是当我尝试调用UsbRequest ur = mConnection.requestWait();函数不返回时,它总是会遇到requestWait().为什么会这样？
