IConnectivityManager 链接电脑，USB数据绑定

Question

浏览了下网页，没有看到相关方面的说明。
其中有些相关方面的接口不知道干嘛用的？
public boolean enableUdcpower(boolean enabled)public boolean enableGser(boolean enabled)public boolean enableVser(boolean enabled)---------------------------------------------
public String[] getTetherableIfaces()public String[] getTetherableUsbRegexs() 
---------------------------------------------
USB 链接电脑，USB数据绑定，可以起作用。
但是点击checbox@Override
public boolean onPreferenceTreeClick(PreferenceScreen preferenceScreen,
Preference preference) {
// TODO Auto-generated method stub
