Hi Pavlya, did you manage to get this working? I have the same problem. I'm using Beaglebone Black running Debian and have Ubuntu 14.04 on my desktop with QT 5.4.1 (x64)(Creator 3.3.1) I can connect from my Desktop using PUTTY or terminal without any problems. BUT I have problems from QT, when I try to Add a kit (Generic Linux Device) it locks when press OK to accept the IP Address and Username etc. This is when it tests the connection to the device. I have reinstalled, I have also tried from another laptop with the same Ubuntu and have the same problems. Any help appreciated. Thanks
