At first, look if your USB port and FTDI device is correctly detected by the router. Some rare FTDI chips are badly detected by the system because are not standard FTDI. Try "cat /proc/bus/usb/devices" to list the USB devices and ports.

If you see the FTDI device in the list, you can try to load the USB modules and FTDI module manually with "modprobe".

Good luck!
