有没有人知道如何在Android上转储设备的HID描述符？我想得到几个HID描述符的解析转储并进行比较。干杯！

Answer 1

您需要使用lsusb command。还有graphical version on GitHub。

Answer 2

如果您使用＆＃39; getevent -S＆＃39;

很容易列出所有输入设备adb shell中的命令如下：

I:\Users\linwei>adb shell getevent -S
add device 1: /dev/input/event6
  name:     "gpio-keys"
add device 2: /dev/input/event2
  name:     "alps"
add device 3: /dev/input/event5
  name:     "7k_handset"
add device 4: /dev/input/event4
  name:     "proximity_sensor"
add device 5: /dev/input/event3
  name:     "accelerometer_sensor"
add device 6: /dev/input/event1
  name:     "7x27a_kp"
add device 7: /dev/input/event0
  name:     "sec_touchscreen"

如果您想查看其中一个的详细信息。使用＆＃39; getevent -i $ eventname＆＃39;像这样显示：

I:\Users\linwei>adb shell getevent -i /dev/input/event1
 add device 1: /dev/input/event1
 bus:      0000
 vendor    0000
 product   0000
 version   0000
 name:     "7x27a_kp"
 location: ""
 id:       ""
 version:  1.0.1
 events:
   KEY (0001): 0072  0073
 input props:
   <none>

因此，只需找到您隐藏设备名称并打印可能的信息。如果要在Android上运行这些命令。您可以使用Runtime执行：

     th = new Thread(new Runnable(){
        private Process exec;

        @Override
        public void run() {

            try {
                exec = Runtime.getRuntime().exec(new String[]{"su","-c","getevent -i " + device});
                InputStreamReader is = new InputStreamReader(
                        exec.getInputStream());

                BufferedReader br = new BufferedReader(is);
                String s;
                while(((s = br.readLine()) != null) && run){
                    ...
                }
                is.close();
                exec.destroy();
            } catch (IOException e) {
                e.printStackTrace();
            } 

        }
