Suddenly there is only one frontend. I think there was two before, frontend0 and frontend1. Not sure when/how the other one got lost. There have been kernel upgrades. More than one. Some upgrade went haywire? All 6 adapters have only one frontend now. Not that I need them desperately, but still ...

I've got a quad around somewhere (I misplaced it). I'll hunt for it again and see what it does in my 4.14 kernels.

I had a 2250 a fewyears ago but returned it because I couldn't get it to work in Linux.

I wonder why you couldn't get it working. It has been working for me for many years, never had any issues. Used to watch analog cable, now I use it for digital broadcast.

I can't find the quad. I'm p.o. ed because I bought it last June for $97 and never used it. I think my wife put in a "safe place" like a black hole.

Good news! After an extended search this morning, She Who Must Be Obeyed asked what I was looking for and then found it immediately. (Yeah! It belongs in a filing cabinet with the furnace papers. Of course!). I'll be installing it later today and will test with a variety of kernels. I have the latest 4.4,4.9. and 4.14 ready in the boot menu.

That's one HVR-1600 and one quad-TV. Looks like thay all take the same driver?

Will reboot and edit with the other two kernels.

Looks like 4.9.66 is not seeing the quad.
