copy d3d11texture from another device - windows

Question

**CopyResource is not woorking,everyone knows why?i have setted GetSharedHandle and OpenSharedResource.
//desc1
m_desc.Width = rendererInfo.SrcBounds.Width;
m_desc.Height = rendererInfo.SrcBounds.Height;
m_desc.Format = rendererInfo.SrcFormat;
m_desc.ArraySize = 1;
m_desc.BindFlags = 0;
m_desc.MiscFlags = D3D11_RESOURCE_MISC_SHARED;
m_desc.SampleDesc.Count = 1;
m_desc.SampleDesc.Quality = 0;
m_desc.MipLevels = 1;
m_desc.CPUAccessFlags = D3D11_CPU_ACCESS_READ | D3D11_CPU_ACCESS_WRITE;
m_desc.Usage = D3D11_USAGE_STAGING;
m_destdesc = m_desc;
//desc2
m_destdesc.Usage = D3D11_USAGE_DEFAULT;
m_destdesc.CPUAccessFlags = 0;
