GL-X750 (spitz) no usb drivers for console adapter?

Technical Support for Routers
1

We are trying to connect an generic Cisco USB-to-Console (RJ45) cable via the USB port but the kernel has no drivers for the usb serial installed?

  1. Latest firmware installed
  2. opkg update/install screen (failed). Screen pkg not found. Need screen pkg for serial console.
  3. dmseg | grep -i tty (failed). Cannot see the usb console cable.

Please help? Thanks.

You should update the repo first.

opkg update

Then install usbutils etc so that you can find out the chipset. Then we can go ahead to install the driver for your adapter.

We have successfully installed “screen” package after “opkg update”.

Here is the output of lsusb -vv for the cisco usb-to-serial-rj45 cable.

We have fixed issue by doing

opkg install kmod-usb-serial-ftdi

Awesome! Thanks.
