gpu calib3d does not work

I am trying to use GPU features of OpenCV for stereo vision, but GPU features of calib3d module does not work on my machine. I have run samples for GPU and the great majority of tests passed (circa 25k), but some has failed (about 370). Most of the tests failed because result matrix was empty. So did all calib3d tests. I am using OpenCV 2.4.9 and CUDA 5.5 but my graphic card supports only CUDA 3.0 or 3.5.

Does anybody know what may be the problem?
