Generic Linux Device and Beaglebone ssh problems

Hello. I encountered a problem. I have Ubuntu 14,04 and Qt 5.4.1 (QtCreator 3.3.2). Also I have Beaglebone. I can connect to Beaglebone via terminal (ssh 192.168.7.2 -l root). But when I do it via QtCreator (Tools->Options->Devices->Add->Generic Linux device) I have got freezed Ubuntu. Mouse and keyboard does not work. In the Generic Linux device I entered the same parameters: IP: 192.168.7.2, login: root, password: not use. I have checked it on Ubuntu 14.04, Ubuntu 14.10, Kubuntu 14.04, Kubuntu 14.10. I got the same freeze system. Also I tried to use several QtCreator (3.0, 3.2, 3.3) This does not solve the problem too.
I would be grateful for any advice
