我目前正在尝试通过 USB 将我的系统（运行 Ubuntu 16.04.3 LTS）绑定到我的三星 Galaxy S7 edge。但是，当我在手机上启用 USB 网络共享时，系统不会连接到它，网络列表中也不会识别新的连接。dmesg启用网络共享时的相关日志如下：
usb 3-4: USB disconnect, device number 52
usb 3-4: new high-speed USB device number 53 using xhci_hcd
usb 3-4: New USB device found, idVendor=04e8, idProduct=6863
usb 3-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 3-4: Product: SAMSUNG_Android
usb 3-4: Manufacturer: SAMSUNG
usb 3-4: SerialNumber: ebb0c96c
rndis_host 3-4:1.0 eth1: register 'rndis_host' at usb-0000:00:14.0-4, RNDIS device, 00:00:00:00:00:00
rndis_host 3-4:1.0 enp0s20u4: renamed from eth1
IPv6: ADDRCONF(NETDEV_UP): enp0s20u4: link is not ready
确实，enp0s20u4在以下方面得到认可ip link：
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
link/ether bc:5f:f4:a2:6a:c3 brd ff:ff:ff:ff:ff:ff
3: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN mode DEFAULT group default
link/ether 02:42:ea:7c:cb:17 brd ff:ff:ff:ff:ff:ff
10: enp0s20u4: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff
但是，如上所述，该链接似乎在其他地方无法识别。可根据要求提供进一步的命令输出。
我如何才能通过 USB 正确地将我的系统绑定到手机？
