Hello. Nube here. Has anyone been successful getting both tuners working yet? ATSC for both?

Yes, I got both ATSC tuners working for my Raspberry Pi 3.
I extracted the patch file for kernel 4.2.5 from Dropbox - wintv-dualhd-kernel-4.2.5-2016-08-10.patch.tar.xz
I used the instructions to apply the patch from Kernel building - Raspberry Pi Documentation

sudo apt-get install git bc
git clone --depth 1 -b rpi-4.2.y https://github.com/raspberrypi/linux
cd linux
patch -p1 < ../wintv-dualhd-kernel-4.2.5-2016-08-10.patch
cd linux
KERNEL=kernel7
make bcm2709_defconfig
make -j4 zImage modules dtbs
sudo make modules_install
sudo cp arch/arm/boot/dts/*.dtb /boot/
sudo cp arch/arm/boot/dts/overlays/*.dtb* /boot/overlays/
sudo cp arch/arm/boot/dts/overlays/README /boot/overlays/
sudo scripts/mkknlimg arch/arm/boot/zImage /boot/kernel7.img

After rebooting with the patched kernel, the two ATSC tuners appeared.

Hi Crazycat,
is this for twin tuner support or ATSC?

There is single tuner support for ATSC.
[v3,2/2,media] em28xx: support for Hauppauge WinTV-dualHD 01595 ATSC/QAM - Patchwork
Hopefully with the patch listed above and the patches listed here, someone can get both ATSC tuners working.
I got both ATSC tuners working on my Raspberry Pi 3 running on a patched kernel 4.2.8.
Raspberry Pi 3 has updated Raspbian from kernel 4.4.x to 4.9.x.

What OS install did you use? It doesn't seem like you're running an LE build.

No. I was not using the LE build because of all the warnings that the WinTV-DualHD ATSC would not work with that current build. I am too much of a newbie to fix the source for lgdt3306a. I am hoping that the LE build will work in the future. The instructions for building the Raspbian Linux kernel listed above was for the Raspberry Pi 3. Here is the reference: Kernel building - Raspberry Pi Documentation

This adds support for DVB only! I am in the UK so do not have a need for ATSC nor have any means for testing it. The amended code for ATSC is in my patch, but it has been commented out and has not been tested. The source for lgdt3306a would need to be amended to get ATSC working and I have not touched this. So to reiterate ATSC will NOT work with this patch. Do not try it.

Any ideas on how to get the ATSC working with your patch?

Thanks Puffin Chunks for your detailed instructions so I can use the workaround to get both of my WinTV-DualHD ATSC tuners working on my Raspberry Pi 3

I got the patch file for kernel 4.2.5 that was mentioned earlier at Dropbox - wintv-dualhd-kernel-4.2.5-2016-08-10.patch.tar.xz

I followed your suggestion as well as Kernel building - Raspberry Pi Documentation

sudo apt-get install git bc
git clone --depth 1 -b rpi-4.2.y https://github.com/raspberrypi/linux
cd linux
patch -p1 < ../wintv-dualhd-kernel-4.2.5-2016-08-10.patch
cd linux
KERNEL=kernel7
make bcm2709_defconfig
make -j4 zImage modules dtbs
sudo make modules_install
sudo cp arch/arm/boot/dts/*.dtb /boot/
sudo cp arch/arm/boot/dts/overlays/*.dtb* /boot/overlays/
sudo cp arch/arm/boot/dts/overlays/README /boot/overlays/
sudo scripts/mkknlimg arch/arm/boot/zImage /boot/kernel7.img

I am now enjoying having both ATSC tuners working.
