usb0網路介面起不來

我已將嵌入式板連接到usb0Linux 機器的介面以ssh與其建立連接。

ifconfig告訴我：

usb0      Link encap:Ethernet  HWaddr 16:43:4D:AA:E8:5A
          inet addr:192.168.2.5  Bcast:192.168.2.255  Mask:255.255.255.0
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

但這不是「運行」。如何啟動該介面？司機失蹤了嗎？lsusb找到設備。該設備本身運行 Yocto Linux。

當您啟動核心時，您是否看到過類似如下的訊息。如果是，假設您已經正確安裝了 linux 驅動程式。

asix 3-3:1.0 eth0：在 usb-0000:00:14.0-3 處註冊“asix”，ASIX AX88772B USB 2.0 以太網，00:0e:c6:c0:d0:5e

接下來，請使用以下命令檢查連結狀態，確保實體連結已啟動並且連接良好。請幫忙貼上您的測試日誌，我可以根據您的設定獲取更多資訊。

我認為他問的是如何調出usb0介面：

sudo ifconfig usb0 up

root 必須運行這個，sudo 是可選的，這取決於你是誰。您可以透過 來了解whoami。
