| This guide provides instructions and a code snippet for developers on how to programmatically detect the connection of a UU cable. This functionality is essential for applications that need to respond to hardware changes dynamically.
| |
| == Implementation Steps: ==
| |
| # '''Understand the Context:'''
| |
| #* The detection of a UU cable connection is typically handled within the application's code, allowing the app to perform specific actions when the cable is connected or disconnected.
| |
| # '''Code Snippet:'''
| |
| #* Below is an example snippet that demonstrates how to detect a UU cable connection within your application.
| |
| <syntaxhighlight lang="java">
| |
| /** | |
| * Obtain whether the UU cable is connected to the terminal.
| |
| * 1,getSystemService(Context.USB_SERVICE);
| |
| * 2,getDeviceList();
| |
| * 3,finding UU cable features;
| |
| */
| |
| /**
| |
| * UU Cable UsbDevice info :
| |
| * [mName=/dev/bus/usb/001/002,
| |
| * mVendorId=1659,mProductId=8963, 9123, 9155, // UU Cable : vid,pid
| |
| * mClass=0,mSubclass=0,mProtocol=0,
| |
| * mManufacturerName=Prolific Technology Inc. ,
| |
| * mProductName=USB-Serial Controller D, // UU Cable : productName
| |
| * mVersion=1.16,mSerialNumber=null,
| |
| * mConfigurations=[UsbConfiguration[mId=1,mName=null,mAttributes=128,mMaxPower=50,mInterfaces=[
| |
| * UsbInterface[mId=0,mAlternateSetting=0,mName=null,mClass=255,mSubclass=0,mProtocol=0,mEndpoints=[
| |
| * UsbEndpoint[mAddress=129,mAttributes=3,mMaxPacketSize=10,mInterval=1]
| |
| * UsbEndpoint[mAddress=2,mAttributes=2,mMaxPacketSize=64,mInterval=0]
| |
| * UsbEndpoint[mAddress=131,mAttributes=2,mMaxPacketSize=64,mInterval=0]]]]

| UsbManager usbManager = (UsbManager) getSystemService(Context.USB_SERVICE);
| |
| HashMap<String, UsbDevice> deviceList = usbManager.getDeviceList();
| |
| for (UsbDevice device : deviceList.values()) {
| |
| Log.d("getDeviceList", "device.toString:" + device.toString());
| |
| if (device.getVendorId() == 1659
| |
| && (device.getProductId() == 8963||device.getProductId() == 9123||device.getProductId() == 9155)
| |
| && device.getProductName().toLowerCase().contains("serial")) {
| |

| }

| |
| This code snippet serves as a starting point. The exact implementation will depend on the specific requirements and the environment in which the application is running.
