Arduino Duemlova in web editor: port has disappeared from board and port menu

Development Tools Cloud Editor

Hi, I recently started working on an Arduino Duemlova using the Arduino Create Online Editor. My computer is running Linux Ubuntu 12.04 LTS. My browser is Firefox 45.0.1.

Everything was fine for a couple days and I made a couple simple programs to blink some LEDs and do some simple math. Then suddenly the editor stopped recognizing the device. In the board and port drop down menu there is no option to select the port. A day later I tried it again and the port was suddenly there again, so I went back to programming and about an hour later the port disappeared again. Here's some info from the rudimentary troubleshooting I've done.

-I've done all the obvious stuff: restarted the computer, unplugged the board, hit reset on the board.

-Switching USB ports does not fix it.

-The USB port does work. I can plug an external hard drive or a keyboard into it and its fine.

-The computer seems to be recognizing the board. When I run lsusb on the terminal I get the device
ID 0403:6001 Future Technolgy Devices International Ltd FT232 USB-Serial (UART) IC
which I'm pretty sure is the Arduino board. Most of the similar forum topics I've found are where the computer itself is not recognizing the board so I think my issue is different. I found this topic
https://forum.arduino.cc/index.php?topic=450551.0
which seems to be the same problem with no solution except that it just started working again, which would be fine except my problem seems to be stuck in the broken state.

-Running the debug console gives me this repeating output
{ "Ports": [], "Network": true }
{ "Ports": [ { "Name": "/dev/ttyUSB0", "SerialNumber": "", "DeviceClass": "", "IsOpen": false, "IsPrimary": false, "Baud": 0, "BufferAlgorithm": "", "Ver": "1.1.60", "NetworkPort": false, "VendorID": "0x0403", "ProductID": "0x6001" } ], "Network": false }

-I plugged the board into an old macbook and same thing. System profiler sees the board but Arduino Create doesn't

Thanks in advance for any advice and let me know if there's other information I can provide.

Does this also occur with the standard IDE or is it specific to the Arduino Web Editor?

Thanks. I hadn't tried the IDE. Just downloaded it and it recognizes the port and I'm able to upload fine so far. Still would love to figure out what the problem is with the online editor.

I'm glad to hear you at least have something working now. I agree that you should be able to get the Arduino Web Editor working. I suggested you try the standard IDE because that gives you some useful information for troubleshooting. You now know this problem is not caused by a hardware issue since you are able to successfully upload so you've narrowed down the potential causes significantly.

Hi @hackofall, do you mean 'Arduino Duemilanove'? can you see at least 'Board' in the dropdown menu?
