Hello, I am new to arduino. I recently just purchased an Uno (surface mounted version) from sparkfun. I am following the tutorials from this site ( http://arduino.cc/en/Tutorial/DigitalReadSerial ) and I have ran into an issue on my second lesson. I am able to upload sketches, but I am not able to use the serial monitor. I am wondering where I went wrong on my setup. I get an error as follows:
when I attempt to use it. I am running Ubuntu 10.04 LTS - the Lucid Lynx 64 bit. I have installed thee rxtx package. dmesg shows:
[ 850.430247] usb 4-3: USB disconnect, address 2 [ 863.200575] usb 4-3: new full speed USB device using ohci_hcd and address 3 [ 863.430257] usb 4-3: configuration #1 chosen from 1 choice [ 863.434059] cdc_acm 4-3:1.0: ttyACM0: USB ACM device
My preferences.txt file is pastebin'd here : http://pastebin.com/sH3UPA1k I have attempted to run as root and it did not fix the issue.
sudo aptitude remove brltty
fixed it for me after a reboot just long enough for me to upload another sketch, however the moment I tried to view the serial console I am back where I started from. I am curious to know what boards need to have the firmware updated. I have the smd version and I do not know where the serial number is, or which ones are bad.
sudo lsusb -v -d 2341: | grep bcdDevice
