Raspberry Pi and Teensy 2.0 USB Serial communication

[rodrigoherrera]

I need to communicate with a teensy 2.0, just as an arduino Leonardo connects to the raspberry pi,
I tried the same code that http://www.doctormonk.com/2012/04/raspberry-pi-and-arduino.html is using and it Works with the Leonardo,
but it doesn't with the teensy, why is that?
how can I install a serial driver for the teensy in the raspberry pi?

It Works with the Leonardo and the teensy on Windows.

Thanks a lot in advance,
Rodrigo Herrera

My Raspi and my Teensy 2 work just fine together.

Do you see a /dev/ttyACM0 (or ACM1 or whatever) device on the Raspi?

What is added to dmesg when you plug in your Teensy?
What does "lsusb" say on the Raspi?
Did you set the USB type to serial on Teensy?

I see a /dev/ttyACM0 on the Raspi, I have set the teensy to serial and the onlything that happens when I "ser.readline()" is it keeps waiting and never shows anything


this is what is added to dmesg
