Hi all! I have a very strange problem: My Arduino Uno rev3 was working just fine for months and some minutes earlier /dev/ttyACM0 disappeared (I’m running on a Linux PC). I unplugged the USB cable and plugged it back, but nothing! I tried:
ls /dev | grep tty | wc
and there’s no device appearing when I unplug the USB cable from the board and I plug it back. Is it dead? Any ideas?
I also restarted the computer… nothing!
Note: There is some program on the chip and it’s running fine.
