@Lazar-Demin Thanks for the info... I was suspecting something like that :-)

RE: Are there serial pins on the expansion dock?
It's amazing the power of comunicating arduino and omega, but I have a situation I don't understand. Probably I'm missing something :-)
I've connected my arduino with omega this way:
ard tx -> omg tx
ard rx -> omg rx
ard vin -> omg 5v
ard gnd -> omg gnd
Then I ssh omega and "screen /dev/ttyATH0 115200" (I configured arduino serial to 115200 to).
Then everything works fine. I receive some data from my dht11 connected to arduino.
So I had the idea of cutting a USB cable and wiring omega usb to arduino this way:
omg usb 5v -> ard 5v
omg usb gnd -> ard gnd
omg usb d+ -> ard tx
omg usb d- -> ard rx
I've tried "usb d+ -> ard rx" and "usb d- -> ard tx" too.
And when I "screen /dev ttyATH0 115200" on my omega I get nothing.
So my question is: Should I receive something? Am I doing something wrong? Any Idea? :-)
