Connecting the mbed to a usb router

21 Feb 2012

Hi Everyone,

I've been using the mbed mostly on Windows and I have a pretty good idea how the USB serial works, however, when it comes to using the USB serial port on Linux/UNIX, I have no clue. The handbook on the website just says to plug it in and it will work :)

I am want to connect the mbed to my router (ASUS RT-N16) which has 2 USB ports. I am running TomatoUSB which supposedly has USB-Serial drivers for ftdi, and a general usbserial.o driver.

I've loaded all usb-serial drivers and I am not getting the serial device to show up. The usb storage does mount. I have a feeling that I am not using the correct kernel module..

What sort of driver does the mbed usb uart need?

It shows up under linux as /dev/ttyACM0 so I guess you need the cdc acm module.

Yup. That did it..
