[BeagleBone Revision 3] Ubuntu 13.04 FTDI Driver ISSUE

Hi guys, I need some help!

I’ve got a beagle bone revision 3 and I’m using Ubuntu 13.04 on my computer. I read the starting guide and I ran the mkudevrule.sh script from the official site, however, some issues still bothering me. Every time when I connect my board to the computer I’ve got the problem that disconnect FTDI USB device from ttyUSB. The research I’ve done pointed out that the problem would be the brltty application on Ubuntu, but I have removed it and the problem still here. Here is the output of the dmesg command.

This is the only issue that I got, the board itself is booting correctly and It’s also got an IP address. If I can’t solve that problem I’m thinking about put a SSH server application directly on the micro-sd card, so I could use the Ethernet interface instead of the USB. But I’ll use this workaround as a last resource option.
