Constructors Summary

public UsbDevice(String name, int vendorId, int productId, int Class, int subClass, int protocol, String manufacturerName, String productName, String serialNumber) UsbDevice should only be instantiated by UsbService implementation hide mName = name; mVendorId = vendorId; mProductId = productId; mClass = Class; mSubclass = subClass; mProtocol = protocol; mManufacturerName = manufacturerName; mProductName = productName; mSerialNumber = serialNumber;

Methods Summary
public int	describeContents() return 0;
public boolean	equals(java.lang.Object o) if (o instanceof UsbDevice) { return ((UsbDevice)o).mName.equals(mName); } else if (o instanceof String) { return ((String)o).equals(mName); } else { return false; }
public UsbConfiguration	getConfiguration(int index) Returns the {@link UsbConfiguration} at the given index. return the configuration return (UsbConfiguration)mConfigurations[index];
public int	getConfigurationCount() Returns the number of {@link UsbConfiguration}s this device contains. return the number of configurations return mConfigurations.length;
public int	getDeviceClass() Returns the devices's class field. Some useful constants for USB device classes can be found in {@link UsbConstants}. return the devices's class return mClass;
public static int	getDeviceId(java.lang.String name) return native_get_device_id(name);
public int	getDeviceId() Returns a unique integer ID for the device. This is a convenience for clients that want to use an integer to represent the device, rather than the device name. IDs are not persistent across USB disconnects. return the device ID return getDeviceId(mName);
public java.lang.String	getDeviceName() Returns the name of the device. In the standard implementation, this is the path of the device file for the device in the usbfs file system. return the device name return mName;
public static java.lang.String	getDeviceName(int id) return native_get_device_name(id);
public int	getDeviceProtocol() Returns the device's protocol field. return the device's protocol return mProtocol;
public int	getDeviceSubclass() Returns the device's subclass field. return the device's subclass return mSubclass;
public UsbInterface	getInterface(int index) Returns the {@link UsbInterface} at the given index. For devices with multiple configurations, you will probably want to use {@link UsbConfiguration#getInterface} instead. return the interface return getInterfaceList()[index];
public int	getInterfaceCount() Returns the number of {@link UsbInterface}s this device contains. For devices with multiple configurations, you will probably want to use {@link UsbConfiguration#getInterfaceCount} instead. return the number of interfaces return getInterfaceList().length;
private UsbInterface[]	getInterfaceList() if (mInterfaces == null) { int configurationCount = mConfigurations.length; int interfaceCount = 0; for (int i = 0; i < configurationCount; i++) { UsbConfiguration configuration = (UsbConfiguration)mConfigurations[i]; interfaceCount += configuration.getInterfaceCount(); } mInterfaces = new UsbInterface[interfaceCount]; int offset = 0; for (int i = 0; i < configurationCount; i++) { UsbConfiguration configuration = (UsbConfiguration)mConfigurations[i]; interfaceCount = configuration.getInterfaceCount(); for (int j = 0; j < interfaceCount; j++) { mInterfaces[offset++] = configuration.getInterface(j); } } } return mInterfaces;
public java.lang.String	getManufacturerName() Returns the manufacturer name of the device. return the manufacturer name return mManufacturerName;
public int	getProductId() Returns a product ID for the device. return the device product ID return mProductId;
public java.lang.String	getProductName() Returns the product name of the device. return the product name return mProductName;
public java.lang.String	getSerialNumber() Returns the serial number of the device. return the serial number name return mSerialNumber;
public int	getVendorId() Returns a vendor ID for the device. return the device vendor ID return mVendorId;
public int	hashCode() return mName.hashCode();
private static native int	native_get_device_id(java.lang.String name)
private static native java.lang.String	native_get_device_name(int id)
public void	setConfigurations(android.os.Parcelable[] configuration) Only used by UsbService implementation hide mConfigurations = configuration;
