linux - 如何从USB端口连接到RJ45控制台设备？

标签 linux ubuntu hardware fedora router

在我的 Linux 笔记本电脑中，USB 端口通过控制台端口(RJ45、Juniper SRX210)连接到外部路由器。这是我正在使用的电缆:

我用过cuteCom enter image description here 我用的是迷你电脑 enter image description here

使用 9600 连接，但它无法识别/dev/ttyS0。还使用 USBViewer ( http://www.kroah.com/linux-usb/ ) 进行了测试，它给出了错误“无法打开文件/proc/bus/usb/devices”

如何才能成功连接？这是我的 lsusb 和 lsusb -v
