带HID USB的Android [英] Android with HID USB

问题描述

亲爱的所有人;



我有一个HID USB设备，我使用c＃构建了一个Windows应用程序，然后在添加VendorID和ProductID后成功连接，类的设备= 03，subClass = 01，Portocol = 0;



我尝试在Android上构建应用程序并尝试连接它之后，检测到它移动，但在我的应用程序中它没有被检测到，但我已经尝试了其他设备Class = 02和Class = 01他们被检测到，



所以我搜索了我有发现Class03被用作Android USB常量，因此它将被列入黑名单，因此我要求制造商将固件更改为class = 01，并且在完成它之后，仍然无法正常工作。



有一个我的应用程序代码示例：

Dear All;

I got an HID USB device , I build for it a windows application using c# then it was connected successfully after adding its VendorID and ProductID, the Device of Class=03,subClass=01,Portocol=0;

after I try to build an Application on Android and try connecting it , it was detected on the Mobile but in my application it was not detected, But I have tried other device of Class=02 and Class=01 they was detected ,

So I searched and I have found that Class03 was used as Android USB constant so it will be blacklisted , so I asked the manufacture to change the Firmware to class=01 and after they have done it , also still not working .

there is a sample of my application code :

if (myUsbManager == null)
              return;

          HashMap<String, UsbDevice> deviceList = myUsbManager.getDeviceList();
          if (!deviceList.isEmpty()) { // deviceList
              StringBuffer sb = new StringBuffer();
              for (UsbDevice device : deviceList.values()) {
                  sb.append(device.toString());
                  sb.append("\n");
                  edtText.setText(sb);

                  mLog("DeviceInfo: " + device.getVendorId() + " , "
                          + device.getProductId());

                  if (device.getVendorId() == VendorID
                          && device.getProductId() == ProductID) {
                      myUsbDevice = device;
                      mLog("USB DEVICE SAME VENDOR ID");
                  }
              }
          }

所以我对我的代码有疑问有一个问题或这个设备不兼容，但为什么它在c＃应用程序上读取但在Android应用程序上没有。或者我还需要在我的apk中添加设置



请注意，我已经尝试过我的apk连接到智能卡读卡器，USB主机，蓝牙设备等等设备和所有都是class = 01和class = 2并且正在读取。

So I was in doubt if my code have an issue or this device in not compatible , but why it was read on the c# application but not on Android application . or is there anymore settings I have to add in my apk

Note that I have tried my apk to connect to Smartcard reader , USB Host , bluetooth devices , and many other devices and all was of class=01 and class=2 and was being read .

推荐答案

if (myUsbManager == null)
                return;

            HashMap<String, UsbDevice> deviceList = myUsbManager.getDeviceList();
            if (!deviceList.isEmpty()) { // deviceList
                StringBuffer sb = new StringBuffer();
                for (UsbDevice device : deviceList.values()) {
                    sb.append(device.toString());
                    sb.append("\n");
                    edtText.setText(sb);

                    mLog("DeviceInfo: " + device.getVendorId() + " , "
                            + device.getProductId());

                    if (device.getVendorId() == VendorID
                            && device.getProductId() == ProductID) {
                        myUsbDevice = device;
                        mLog("USB DEVICE SAME VENDOR ID");
                    }
                }
            }
