Arduino IDE does not start when UMTS stick is connected under Linux.

Hi Forum,

I searched the Internet and this forum and didn't find an answer for my Question, so please forgive me, if I just searched by using the wrong keywords.

I don't have wifi at the moment and have to use a Huawai UMTS Stick to go online. If I do so, the Arduino IDE is not working anymore. Even if the correct tty-Device is configured in the conf file.

The Huawei device creates three ttyUSBs with numbers depending on the order the devices are plugged in: If I am already online having plugged in the Huawei first, there is
/dev/ttyUSB0
/dev/ttyUSB1
/dev/ttyUSB2

If I then plug in my Arduino (or my FTDI breakout board, or my CP2102 Converter ...) there is another tty:

/dev/ttyUSB3

in that state the IDE does not startup or to put it that way: it starts and immediately crashes without an error message.

Now I disconnect the UMTS device, the ttyUSB3 remains as it was, but now my IDE will start up.

So, is there any way of forbidding the IDE to talk to the wrong ttys?

Btw: If the IDE is already running, it will crash immediately, when I click on the "Tools" menu item.

Unfortunately, I do not know what is the real solution for this problem but this post have been very useful (I have ZTE MF668A, Ubuntu 11.10).

The IDE had not start until I found this post and started to remove 3G dongle during Arduino programming. (I always had buffer overflow: ArduinoIDE - Pastebin.com)

Yes it is exacly the same Problem I have.

I found out, that the 3G-Connection has to be up and running to cause the problem. If the Dongle is pluged in and offline, there is no problem.

I reported this as a Bug:

WelcomeI also have the same problem with Arduino and 3G/4G modem
Arduino 1.0.4 64bit
archlinux 64bit
3.8.8-1-ARCH
[foreste@dom arduino-1.0.432]$ arduino Experimental: JNI_OnLoad called.WARN - Pastebin.com dump console
Modem Huawei 173.

Hi,
same problem on UBUNTU 12.10 with modem ZTE MF190
