請問移植wifi的android UI是否產生兩個以上device

如題，如果小弟外接usb hub，接上兩個usb wifi，在命令模式下會產生 兩個device，但是UI同樣會有嗎？
順便問：如果在命令模式下iwlist wlan0 scan可以正常掃描出AP
但是UI，除非下iwlist wlan0 scan，否則UI永不顯示掃描出AP的狀況，如何改善(使用友善提供的wpa_supplicant_6，因為使用wpa_supplicant_5的話，UI會直接顯示error)


查看了<android>/frameworks/base/services/java/com/android/server/WifiService.java 中有

    private static final int MESSAGE_ENABLE_WIFI        = 0;
    private static final int MESSAGE_DISABLE_WIFI       = 1;
    private static final int MESSAGE_STOP_WIFI          = 2;
    private static final int MESSAGE_START_WIFI         = 3;
    private static final int MESSAGE_RELEASE_WAKELOCK   = 4;
    private static final int MESSAGE_UPDATE_STATE       = 5;
    private static final int MESSAGE_START_ACCESS_POINT = 6;
    private static final int MESSAGE_STOP_ACCESS_POINT  = 7;
    private static final int MESSAGE_SET_CHANNELS       = 8;
    private static final int MESSAGE_ENABLE_NETWORKS    = 9;
    private static final int MESSAGE_START_SCAN         = 10;
    private static final int MESSAGE_REPORT_WORKSOURCE  = 11;
    private static final int MESSAGE_ENABLE_RSSI_POLLING = 12;

但是似乎沒有看到實作....
