RTL8188CUS 802.11n WLAN 适配器在接口文件中自动配置

Question

我买了一个 USB WIFI 适配器，名为“EDUP”：

（瑞昱半导体公司 RTL8188CUS 802.11n WLAN 适配器）

所以我通过这种方式配置了该文件：

# The loopback network interface
auto lo
iface lo inet loopback

#auto usb0
#iface usb0  inet static
#  adress 192.168.7.2
#  netmask 255.255.255.0
#  network 192.168.7.0
#  gateway 192.168.7.1
#  broadcast 192.168.7.255
# dns-nameservers 8.8.8.8 8.8.4.4

    #allow-hotplug wlp2s0
    #iface wlp2s0 inet dhcp

    auto wlan0
    allow-hotplug wlan0
    iface wlan0  inet dhcp
       wpa-ssid "roshd"
       wpa-psk "rr1393"

的输出如果配置是 ：

usb0: flags=-28605<UP,BROADCAST,RUNNING,MULTICAST,DYNAMIC>  mtu 1500
        inet 192.168.7.1  netmask 255.255.255.0  broadcast 192.168.7.255

这LSSB输出也是：

我已经运行了 apt-get 更新通过此配置，该设备不会显示在我的 (LINUX MINT LMDE) 的网络面板中：

但是当我从文件中删除这些行时， /etc/network/interfaces无线图标显示我的 USB DONGEL 并且它正在工作：

 auto wlan0
    allow-hotplug wlan0
    iface wlan0  inet dhcp
       wpa-ssid "roshd"
       wpa-psk "rr1393"

，但我想为我的树莓派配置它，并且我需要使用该 /etc/network/interfaces文件。

那么我必须做什么才能自动在 /etc/network/interfaces 文件中配置它？

更新：

现在，当我删除这些线时，我也无法访问我的 USB 加密狗，如您所见：

谢谢
