debian 64bit and tx led always on


I'am trying debian 64bit with Arduino uno, but the tx led is alway on and I can't update my program.
The same Arduino Uno works fine with Windows.

I found some old threads that suggests updating the firmware. My firmware is rev. 0001, do I really need to update it?

I hope some debian user can help me.

Sorry for my bad english.


In the program there was a Serial.print inside a loop that send message through the usb without any delay.
The problem was solved by putting a delay(2000) before the Serial.print.

Here the topic in italian forum Arduino Forum.
