I know this has been asked before, but no one's solutions I've seen have worked so far. I just got started with Arduino and downloaded Arduino IDE from the Software Center. When trying to to set up my Serial Port, the option in the toolbar is gray/unaccessible.
I also downloaded it as a tar.xz instead of from the Software Center and had the same problem.
When I plug in my Uno, the green light turns on so I know it's being connected at least.
One solution I saw said it was a problem with my user group. However, I entered
sudo groups <username>
and came up with <username> tty dialout sudo audio video plugdev input
so I think my groups are okay, right?
Anyway, I would really appreciate some help if anyone knows of a fix. I run 12.04 Ubuntu (I recently re-installed trying to fix this problem; I'm going to update to 14.04) on a Chromebook.
ls -l /dev/ttyUSB*andls -l /dev/ttyACM*(done while the board is connected) into your question. Also if you recently changed any group memberships make sure you have logged out (or more simply, rebooted) since. – Chris Stratton May 24 at 2:11ls -l /dev/ttyUSB*as well asls -l /dev/ttyACM*into my terminal and it simply said it was not a directory. Thanks for commenting. – Jakob Klemm May 24 at 2:22lsusbwhen it is and isn't connected, or you can check for error messages shortly after connection withdemsg. At this point it could be anything - bad board, bad cable, damaged connector, missing kernel modules, or bad/atypical rules for udev or similar. – Chris Stratton May 24 at 2:30/devthe only "tty" files I have are "tty" and "tty8." Does it seem like I'm missing something? EDIT: I damaged one of my USB ports last year, though I'm using the other one so I don't think it's that. Thanks anyway – Jakob Klemm May 24 at 2:32
