我就是單純的覺得網線接口插拔太麻煩，所以在淘寶買了usb轉RJ45的接口轉換器：https://detail.tmall.com/item.htm?id=524808012954&ali_refid=a3_430582_1006:1105586579:N:USB%E6%97%A0%E7%BA%BF%E7%BD%91%E5%8D%A1%20%E7%AC%94%E8%AE%B0%E6%9C%AC:eb696d88976cbb7272321d0ffa0bb488&ali_trackid=1_eb696d88976cbb7272321d0ffa0bb488&spm=a230r.1.14.1
就是這貨，ubuntu中使用還沒有驅動~問了客服，表示可以自己下載驅動：
但是，直接make后ismod模塊還報錯！
安裝驅動時報錯Unknown symbol in module解決方案：
root@ubuntu:/mnt/hgfs/share/LinuxDriver/download/r8152-2.09.0# make //編譯 make -C /lib/modules/4.4.0-109-generic/build SUBDIRS=/mnt/hgfs/share/LinuxDriver/download/r8152-2.09.0 modules make[1]: Entering directory '/usr/src/linux-headers-4.4.0-109-generic' CC [M] /mnt/hgfs/share/LinuxDriver/download/r8152-2.09.0/r8152.o Building modules, stage 2. make[2]: Warning: File '/mnt/hgfs/share/LinuxDriver/download/r8152-2.09.0/r8152.o' has modification time 1.5 s in the future MODPOST 1 modules CC /mnt/hgfs/share/LinuxDriver/download/r8152-2.09.0/r8152.mod.o LD [M] /mnt/hgfs/share/LinuxDriver/download/r8152-2.09.0/r8152.ko make[2]: warning: Clock skew detected.

參考：http://blog.csdn.net/zhang_danf/article/details/17758669
dmesg | tail 看輸出信息中的Unknown symbol，加載上這些模塊就好。我的輸出信息是：
root@ubuntu:/mnt/hgfs/share/LinuxDriver/download/r8152-2.09.0# dmesg | tail [38227.073922] IPv6: ADDRCONF(NETDEV_UP): ens33: link is not ready [38227.073934] IPv6: ADDRCONF(NETDEV_CHANGE): ens33: link becomes ready [38448.591972] r8152: Unknown symbol mii_nway_restart (err 0) [39883.931152] xhci_hcd 0000:03:00.0: Error: Failed finding new dequeue state [39886.445089] usb 3-2: USB disconnect, device number 5 [39886.445375] pl2303 ttyUSB0: pl2303_set_control_lines - failed: -19 [39886.445379] pl2303 ttyUSB0: error sending break = -19 [39886.446493] pl2303 ttyUSB0: pl2303 converter now disconnected from ttyUSB0 [39886.446509] pl2303 3-2:1.0: device disconnected [40375.871882] r8152: Unknown symbol mii_nway_restart (err 0)
估計是由於模塊依賴的其他模塊沒有加載導致的。
直接用modinfo ./r8152.ko | grep depend命令查找模塊的依賴，結果如下：
root@ubuntu:/mnt/hgfs/share/LinuxDriver/download/r8152-2.09.0# modinfo ./r8152.ko | grep depend depends: mii root@ubuntu:/mnt/hgfs/share/LinuxDriver/download/r8152-2.09.0# modprobe mii root@ubuntu:/mnt/hgfs/share/LinuxDriver/download/r8152-2.09.0# insmod r8152.ko root@ubuntu:/mnt/hgfs/share/LinuxDriver/download/r8152-2.09.0#
模塊加載成功了~
如果這樣就能用，似乎太簡單了：
結果還是不能用：
然后，重啟虛擬機，再拔出usb轉RJ45轉接器重新插上，Vmware就可以識別了：
關於dmesg命令，這個寫的很清楚：
https://linux.cn/article-3587-1.html
問題又出現了，雖然驅動安裝成功，但是實際測試並不能用啊：通過dmesg | grep usb 查看內核打印信息錯誤是device descriptor read/64, error -110：

查看內核錯誤碼發現問題是連接超時：為啥會連接超時？？這也不算是找到根源啊，沒法解決~
經過一番百度，受文章啟示（如下圖說明）(問題鏈接：http://www.ceus-now.com/ubuntu-can-t-read-my-usb-device-descriptor-read-64-error-110/)感覺有可能是硬件問題，電壓問題還是啥的反正沒搞明白，按照他說的操作，把虛擬機和筆記本電腦都重啟了同時把usb轉RJ45的接口轉換器插到usb擴展接口的另外一個接口，然后就可以正常使用了~
