@srkarpyn thanks very much for your response. I’m happy to report that I have this week found a solution that works for me! I can only hope it also works for you. I noticed this other thread with a similar issue and it contained an extra step I hadn’t seen mentioned anywhere else.
Adding those two firmware files made everything immediately work for me. w_scan finds channels, Plex finds channels and I can now use the DVR functionality as expected. I’ve made a number of successful recordings. I am going to report this information back to Hauppauge and suggest they include it on their Linux setup pages.
Note I am running Ubuntu Server, and the poster of that solution suggests adding the firmware files is only necessary on the Server edition. (Are you running Server…?)
I hope that helps you. Just let me know if I can give you any further information about my setup that may help you. Good luck!
