Connect Arduino to a Embedded Linux - Serial Port not found

Development Tools IDE 1.x

Hi all.

We are starting a project here at RoboSavvy.com to include a Arduino + Linux + Camera into a VEX robotics kit, you can check the project here http://robosavvy.com/forum/viewtopic.php?t=7397

Right now I'm stucked as the Linux does not 'detect' the Arduino that's connected through the USB port, here is the output of dmesg and lsubs commands:

root@OpenWrt:~# dmesg

As you can see the Arduino UNO is detected but no serial port in created.

Anyone with a solution?

Is your kernel compiled with the 'cdc-acm' drivers?

hey,
maybe you need to change the firmware on your 8u2 chip. My uno started working again after following these steps here :

Hope it helps.
