I am a Plex pas subscriber and running Plex version 1.7.5.4035 and Ubuntu version 16.04.2 I have two Hauppauge tuners, the xbox tuner from Hauppauge works fine but the WinTV-dualHD does not show up. I did run lsusb and it does recognize that a Hauppauge tuner is plugged in. I followed the Plex and Hauppauge instructions and the Tuner TV install with PPA and have had no luck http://www.hauppauge.com/site/support/linux.html.
I have tested it on my Windows laptop and both tuners work fine, it also works on my Shield TV as well.
yes they are supported it’s the happauge win-tvdualhd it looks like I need to go back to an older kernal version of 16.4 Ubuntu. I am going to do that when I get home.
Edit: I will update this once I get home and do that.
Thank you for your answers, the issue was that I had a version of linux kernel that was not supported. I have it working fine now. I decided to go with ubuntu 17 so I did not need to worry about updates changing my kernel version on ubuntu 16.4 lts
