Error OpenCV with CUDA using TBB for multiple GPUs

My OpenCV CUDA program runs fine using a single NVidia 580GTX, but when using another, it gives the following error:

OpenCV Error: Gpu API call (invalid device ordinal) in mallocPitch

I know I need TBB to assign a GPU its job, but even though I installed OpenCV with TBB support (followed the willowgarage website), it says TBB support is required (CMake key 'WITH_TBB' must be true). Any help would really be appreciated since I need this to complete my computer science Master's project.

Thanks!

Ok its solved. turns out it was build 7232 that was the problem, since it works with the latest opencv build(7292) with no problems. Thanks all for the support
