I recently purchased an Arduino Uno R3 board, and I connected it to my Laptop running Fedora 16 (64bit) with my old (no longer used) printer's USB cable.
I was able to connect it, but for a few times, the IDE (0022) showed my serial port disabled in the tools. Funnily, when I ran the ide as root, the port became magically available.
I sorted this issue by adding myself to the lockout and dial user groups, as suggested by the ide
I was able to run a led blink program on arduino without probs for 2 days
However, just today, A wierd issue started cropping up.
The serial Port stays disabled. no matter whether Im root or normal user. Moreover, Sometimes, when I connect the device to lappie, the power and led 13 keep blinking simultaneously, with interval of about 100 ms, 4 to 6 times, and go off altogether, like it isn't connected at all.
I am guessing that this is an issue with the cable, and am in the process of procuring a new cable. But just to make sure that this is not some other problem altogether, Im posting this here.
These are the messages i get in /var/log/messages when I plug the cable to the PC.
