如何從USB端口連接到RJ45控制檯設備？

在我的Linux筆記本電腦中，USB端口通過控制檯端口（RJ45，Juniper SRX210）連接到外部路由器。這是我使用的電纜：如何從USB端口連接到RJ45控制檯設備？

enter image description here

我用cuteCom enter image description here 我用小型機 enter image description here

要使用9600連接，但它不能識別的/ dev/ttyS0來。還使用USBViewer（http://www.kroah.com/linux-usb/）進行了測試，該錯誤顯示「無法打開文件/ proc/bus/usb/devices」

如何使此連接成功？這是我和的lsusb -v的lsusb

你插入了串口適配器嗎？ –

@Ignacio Vazquez-Abrams：它的USB（公）電纜末端有RJ45公頭（連接到路由器的串行控制檯端口，這是一個RJ45母頭） – YumYumYum

您的'lsusb'輸出不顯示任何東西，只有一個鼠標插入。您確定另一端的設備是否已啓用USB存取功能？ –

ttyS0是系統的第一個RS-232端口，你很可能尋找ttyUSB0

錯誤的電纜。這根電纜適用於掃描儀。從USB信號轉換爲串行信號是通過嵌入在插頭內部的UART電路完成的。請參閱 FTDI USB轉RS232串口轉RJ45 CAT5控制檯適配器電纜，用於思科路由器 在ebay上。然後使用Linux minicom程序。
