背景知识 2 | USB是一种数据通信方式，也是一种数据总线，而且是最复杂的总线之一。 3 | 硬件上，它是用插头连接。一边是公头（plug），一边是母头（receptacle）。例如，PC上的插座就是母头，USB设备使用公头与PC连接。 4 | 目前USB硬件接口分三种，普通PC上使用的叫Type；原来诺基亚功能机时代的接口为Mini USB；目前Android手机使用的Micro USB/TYPE-C。 5 | 6 | #### Host 7 | USB是由Host端控制整个总线的数据传输的。单个USB总线上，只能有一个Host。 8 | #### OTG 9 | On The Go，这是在USB2.0引入的一种mode，提出了一个新的概念叫主机协商协议（Host Negotiation Protocol），允许两个设备间商量谁去当Host。 10 | 11 | 想了解更多USB知识，请参考USB官网以及下面这篇文章： 12 | http://www.crifan.com/files/doc/docbook/usb_basic/release/html/usb_basic.html 13 | 14 | #### USB HOST/DEVICE/OTG概念： 15 | 16 | 1.USB 设备分为 HOST (主设备)和SLAVE (从设备),只有当一台 HOST 与一台 SLAVE 连接时才能实现数据的传输。 17 | (1) USBHOST 是指主机。 18 | (2) USBOTG 设备既能做主机,又能做设备。 OTG 技术就是实现在没有 Host 的情况下,实现从设备间的数据传送。 19 | 当 OTG 插到电脑上时. OTG 的角色就是连接电脑的 device (读卡器),也就是 SLAVE (从设备);当USB/SD device插到 OTG 上, OTG 的角色就是 HOST 主机。（有些手机也经常用到 OTG的功能） 20 | 21 | ### Android使用（Host连接） 22 | 首先应该介绍，USBManager这个类，这个类用于访问USB状态并与USB设备通信。目前只开放HOST模式。 23 | 初始化USBManager mUsbManager = ((UsbManager) context.getSystemService(USB_SERVICE)); 24 | 里面有几个重要的方法： 25 | 26 | 1.getDeviceList()——获取当前USB连接从设备的列表，返回一个存储UsbDevice的HashMap 27 | 2.getAccessoryList()——这个就是获取Host的列表（用不到） 28 | 3.openDevice(UsbDevice)—— 这个方法是USB连接方法，连接成功后会返回一个UsbDeviceConnection对象。 29 | 4.requestPermission(UsbDevice,PendingIntent)——这个方法用于请求USB权限。 30 | 31 | #### 监听USB插入/拔出 32 | 通过广播意图android.hardware.usb.action.USB_STATE，实现插入拔出监听 33 | ```java 34 | class USBStateReceive extends BroadcastReceiver { 35 | public static final String ACTION_USB_STATE = "android.hardware.usb.action.USB_STATE"; 36 | public static final String USB_CONNECTED = "connected"; 37 | private IUsbStateChangeListener mUsbStateChangeListener; 38 | 39 | 40 | public void onReceive(Context paramContext, Intent intent) { 41 | String action = intent.getAction(); 42 | Log.d(TAG, "usb action + " + action); 43 | switch (action) { 44 | case UsbManager.ACTION_USB_DEVICE_ATTACHED: 45 | UsbDevice device = intent.getParcelableExtra(UsbManager.EXTRA_DEVICE); 46 | Log.d(TAG, "device_attached," + device.toString()); 47 | if (mUsbStateChangeListener != null) { 48 | mUsbStateChangeListener.onAttach(device); 49 | } 50 | break; 51 | case UsbManager.ACTION_USB_DEVICE_DETACHED: 52 | device = intent.getParcelableExtra(UsbManager.EXTRA_DEVICE); 53 | Log.d(TAG, "device_detached," + device.toString()); 54 | if (mUsbStateChangeListener != null) { 55 | mUsbStateChangeListener.onDetach(device); 56 | } 57 | break; 58 | case ACTION_USB_STATE: 59 | boolean connected = intent.getBooleanExtra(USB_CONNECTED, false); 60 | break; 61 | } 62 | 63 | } 64 | 65 | public void setUsbStateChangeListener(IUsbStateChangeListener usbStateChangeListener) { 66 | this.mUsbStateChangeListener = usbStateChangeListener; 67 | } 68 | } 69 | 70 | ``` 71 | 这个广播也可以获取到当前插入/拔出的设备信息。可以通过这个广播来监听新插入/拔出的USB设备。 72 | 73 | 74 | #### 当前连接的USB设备 75 | 可以通过getDeviceList获取当前连接的USB设备 76 | 为此我们编写一个USBFinder 用来查找USB设备。 77 | ```java 78 | 79 | package cn.xiaolongonly.usbhelper.usbmodule; 80 | 81 | import android.hardware.usb.UsbDevice; 82 | import android.hardware.usb.UsbManager; 83 | 84 | import java.util.HashMap; 85 | import java.util.Iterator; 86 | 87 | /** 88 | * 89 | * 90 | * @author xiaolong 719243738@qq.com 91 | * @version v1.0 92 | * @since 2019/4/10 15:36 93 | */ 94 | public class USBFinder { 95 | private UsbManager mUsbManager; 96 | private static USBFinder usbFinder; 97 | 98 | private USBFinder(UsbManager usbManager) { 99 | this.mUsbManager = usbManager; 100 | } 101 | 102 | /** 103 | * Application Context; 104 | * 105 | */ 106 | public static void init(UsbManager usbManager) { 107 | usbFinder = new USBFinder(usbManager); 108 | } 109 | 110 | public static USBFinder getInstance() { 111 | if (usbFinder == null) { 112 | throw new RuntimeException("需要在Application中執行USBFinder.init()"); 113 | } 114 | return usbFinder; 115 | } 116 | 117 | public HashMap findUsbMap() { 118 | HashMap deviceMap = mUsbManager.getDeviceList(); 119 | return deviceMap; 120 | } 121 | 122 | 123 | public UsbDevice findUsbDevice(int vendorId, int productId) { 124 | HashMap deviceMap = mUsbManager.getDeviceList(); 125 | Iterator iterator = deviceMap.values().iterator(); 126 | UsbDevice localUsbDevice; 127 | while (iterator.hasNext()) { 128 | localUsbDevice = (UsbDevice) iterator.next(); 129 | if (localUsbDevice.getVendorId() == vendorId || localUsbDevice.getProductId() == productId) { 130 | return localUsbDevice; 131 | } 132 | } 133 | return null; 134 | } 135 | } 136 | 137 | ``` 138 | 1. findUsbMap 用于找到当前已连接的USB设备列表，这个用户选择连接非常有用，比如有多个USB设备，选择一个连接。（跟上一个通过广播监听的区别是，有时候一些USB设备默认是插着的，通过上面的广播并不能知道） 139 | 2. findUsbDevice 遍历设备列表，通过vendorId和productId找到合适的USB设备，通过这个可以省掉让用户选择的过程，如果连接的设备只有一个的话可以直接用这个。 140 | 141 | 142 | #### USB连接，如何确认USB连接及USB授权？ 143 | Android 在USBManager 提供了一个 requestPermission(UsbDevice device, PendingIntent pi)，这个模式是手机作为HOST对设备做授权。 144 | 145 | ```java 146 | public void getPermission(Context context, UsbManager usbManager, UsbDevice usbDevice, final UsbPermissionReceiverListener callBack) { 147 | if (usbManager.hasPermission(usbDevice)) { 148 | callBack.onSuccessful(); 149 | return; 150 | } 151 | mContext = context; 152 | IntentFilter intentFilter = new IntentFilter(); 153 | intentFilter.addAction("com.android.example.USB_PERMISSION"); 154 | mContext.registerReceiver(mUsbReceiver, intentFilter);//注册广播接收者 155 | mUsbReceiver.setUsbPermissionReceiverListener(new UsbPermissionReceiverListener() { 156 | @Override 157 | public void onSuccessful() { 158 | mContext.unregisterReceiver(mUsbReceiver); 159 | callBack.onSuccessful(); 160 | } 161 | 162 | @Override 163 | public void onFail(String msg) { 164 | mContext.unregisterReceiver(mUsbReceiver); 165 | callBack.onFail(msg); 166 | } 167 | 168 | }); 169 | mUsbReceiver.setUsbDeviceName(usbDevice.getDeviceName());//为广播接受者设置DeviceName名称用于与接收的名称进行对比 170 | PendingIntent mPermissionIntent = PendingIntent.getBroadcast(context, 0, new Intent(ACTION_USB_PERMISSION), 0); 171 | usbManager.requestPermission(usbDevice, mPermissionIntent); 172 | } 173 | ``` 174 | 授权广播 175 | ```java 176 | class PermissionReceiver extends BroadcastReceiver { 177 | 178 | protected UsbPermissionReceiverListener mUsbPeramissionRecevierListener = null; 179 | protected String mUsbDeviceName = ""; 180 | 181 | public void onReceive(Context paramContext, Intent intent) { 182 | String action = intent.getAction(); 183 | Log.d(TAG, "usb action + " + action); 184 | 185 | if (intent == null) { 186 | mUsbPeramissionRecevierListener.onFail("授权失败：未知授权申请！"); 187 | } else { 188 | if (ACTION_USB_PERMISSION.equals(intent.getAction())) { 189 | UsbDevice localUsbDevice = intent.getParcelableExtra("device"); 190 | if (localUsbDevice != null) { 191 | if (!(intent.getBooleanExtra("permission", false))) {//用户取消授权 192 | if (this.mUsbPeramissionRecevierListener != null) { 193 | mUsbPeramissionRecevierListener.onFail("用户取消授权，授权失败！"); 194 | } 195 | } else { 196 | String deviceName = localUsbDevice.getDeviceName(); 197 | if (deviceName.equals(this.mUsbDeviceName)) {//若获得的deviceName与_usbDeviceName一致 198 | if (this.mUsbPeramissionRecevierListener != null) { 199 | mUsbPeramissionRecevierListener.onSuccessful(); 200 | } 201 | } else { 202 | if (this.mUsbPeramissionRecevierListener != null) { 203 | mUsbPeramissionRecevierListener.onFail("授權失敗：設備名稱不一致！"); 204 | } 205 | } 206 | } 207 | } else { 208 | return; 209 | } 210 | } else { 211 | mUsbPeramissionRecevierListener.onFail("授權失敗：未知授权申请！"); 212 | return; 213 | } 214 | } 215 | } 216 | 217 | 218 | public void setUsbPermissionReceiverListener(UsbPermissionReceiverListener paramAsyncTaskListener) { 219 | this.mUsbPeramissionRecevierListener = paramAsyncTaskListener; 220 | } 221 | 222 | public void setUsbDeviceName(String usbDeviceName) { 223 | this.mUsbDeviceName = usbDeviceName; 224 | } 225 | } 226 | ``` 227 | 授权广播类，监听的是com.android.example.USB_PERMISSION 228 | 229 | 通过以上几个方法我们可以获取到当前连接的USB设备了，接下来就是建立传输通道 230 | 231 | #### 数据传输 232 | 233 | 这边先要获取一个UsbDeviceConnection 对象， 也就是通过USBManager.openDevice(UsbDevice)获取连接的对象。 234 | 235 | ```java 236 | /** 237 | * 选择USB设备和interface,打开。 238 | * 239 | * @return 240 | */ 241 | public int open(UsbDevice usbDevice, int interfaceIndex) { 242 | mDevice = usbDevice; 243 | if (!setInterface(this.mDevice, interfaceIndex)) { 244 | Log.d(TAG, "interfaceIndex OutOfBound!"); 245 | return -1; 246 | } 247 | this.mInterface = mDevice.getInterface(interfaceIndex); 248 | if (!(setEndpoint(this.mInterface))) { 249 | return -1; 250 | } 251 | this.mDeviceConnection = this.mManager.openDevice(usbDevice); 252 | if (this.mDeviceConnection == null) { 253 | return -1; 254 | } 255 | return 0; 256 | } 257 | ``` 258 | 259 | 讲一下为什么这个类需要传interfaceIndex，一般来讲一个UsbDevice 会有多个UsbInterface， 不同的interface是分开的，有不同的功能。每个UsbInterface又会有多个UsbEndpoint，用于处理输入和输出，也就是数据传输。 260 | 261 | 检验interface和endpoint 是否符合 262 | ```java 263 | protected boolean setInterface(UsbDevice mDevice, int interfaceIndex) { 264 | if (mDevice != null && mDevice.getInterfaceCount() > interfaceIndex) { 265 | return true; 266 | } else { 267 | return false; 268 | } 269 | } 270 | 271 | 272 | /** 273 | * 设置Endpoint,根据Device的Interface 274 | * 275 | * @param paramUsbInterface 276 | * @return 277 | */ 278 | protected boolean setEndpoint(UsbInterface paramUsbInterface) { 279 | if (paramUsbInterface.getEndpointCount() != 2) { 280 | Log.d(TAG, "Endpoint count less than 2.."); 281 | return false; 282 | } 283 | for (int m = 0; m < paramUsbInterface.getEndpointCount(); m++) { 284 | UsbEndpoint ep = paramUsbInterface.getEndpoint(m); 285 | if (ep.getType() == UsbConstants.USB_ENDPOINT_XFER_BULK) { 286 | if (ep.getDirection() == UsbConstants.USB_DIR_OUT) { 287 | this.mEndpointOut = ep; 288 | } else { 289 | this.mEndpointIn = ep; 290 | } 291 | } else { 292 | return false; 293 | } 294 | } 295 | return true; 296 | } 297 | ``` 298 | 299 | 这两个方法就是用来看是不是能找到对应的UsbInterface和UsbEndpoint，因为我们的需求是要这个既有输入又有输出的UsbInterface。所以做了相应的校验。 300 | 301 | 接下来是数据传输 302 | ```java 303 | public void sendData(byte[] data, IDataSendCallBack iDataSendCallBack, int timeOut) { 304 | if (this.mDeviceConnection == null) { 305 | if (iDataSendCallBack != null) { 306 | iDataSendCallBack.onSendResult(CODE_DEVICE_NO_OPEN, null, "未开启设备，请先执行open()！"); 307 | } 308 | 309 | } 310 | this.mDeviceConnection.claimInterface(this.mInterface, true);//调用了本地 311 | bulkTransfer(this.mDeviceConnection, this.mEndpointOut, this.mEndpointIn, data, data.length, timeOut, iDataSendCallBack); 312 | this.mDeviceConnection.releaseInterface(this.mInterface);//释放接口 313 | 314 | } 315 | 316 | protected void bulkTransfer(final UsbDeviceConnection usbDeviceConnection, UsbEndpoint outPoint, final UsbEndpoint inPoint, byte[] datas, int dataLength, final int timeLimit, final IDataSendCallBack iDataSendCallBack) { 317 | int bulkTransferLength = usbDeviceConnection.bulkTransfer(outPoint, 318 | datas, dataLength, timeLimit); 319 | if (bulkTransferLength < 0) { 320 | if (iDataSendCallBack != null) { 321 | iDataSendCallBack.onSendResult(CODE_SEND_FAIL, datas, "发送失败！"); 322 | } 323 | } 324 | if (iDataSendCallBack != null) { 325 | iDataSendCallBack.onSendResult(CODE_SEND_SUCCESS, datas, "發送成功！"); 326 | 327 | } 328 | if (mEndpointIn == null) { 329 | if (iDataSendCallBack != null) { 330 | iDataSendCallBack.onSendResult(CODE_NO_INPOINT, null, 331 | "該interface底下沒有接口端口，无法接收数据！"); 332 | } 333 | } 334 | new Thread(new Runnable() { 335 | 336 | @Override 337 | public void run() { 338 | while (true) { 339 | byte[] inByte = new byte[1024]; 340 | int inLength = usbDeviceConnection.bulkTransfer(inPoint, 341 | inByte, inByte.length, timeLimit); 342 | if (inLength > 0) { 343 | inByte = Arrays.copyOf(inByte, inLength); 344 | if (iDataSendCallBack != null) { 345 | iDataSendCallBack.onSendResult(CODE_DATA_RECEIVE, 346 | inByte, "收到数据！"); 347 | } 348 | } else { 349 | break; 350 | } 351 | } 352 | } 353 | }).start(); 354 | } 355 | ``` 356 | DeviceConnection.claimInterface()占用了这个interface，在发送结束后releaseInterface 相当于释放interface. 357 | 项目要求是一次输入，一次输出。所以每次都会开开合合，如果不是这种需求的话应该可以长期开着等全部结束后关闭，类似于Socket。 358 | 359 | Talk is cheap, here the code.
