Hello, I have found patches that add support for the second tuner: https://github.com/b-rad-NDi/Ubuntu-media-tree-kernel-builder/tree/master/patches/ubuntu-zesty-4.10.0/extra I can confirm that they also work with the latest kernel (4.12.0-rc2). Would it be possible to integrate these patches into mainline? Applying 0006-Hauppauge-WinTV-DualHD-DVB-ATSC-second-tuner-support.patch is sufficient for the second tuner to appear, but I guess we should include all patches.
