Per the linuxtv.org page you refer to, it looks like I need 4.11,
so I added stretch-backports and I'm DLing it as I type.

Mine says: ID 2040:026d. Lsusb -v doesn't return a Model, the closest
thing is "iProduct 1", but in /var/log/messages this shows up:
kernel: [435914.846896] usb 1-6: Product: 955D
kernel: [435914.846900] usb 1-6: Manufacturer: HCW
kernel: [435914.846903] usb 1-6: SerialNumber: 0013946375
So it looks like I have a model 1595, per the linuxtv.org page

That's disappointing. I wonder if that's the case for all multiple-tuner
Hauppauge products. Elsewhere someone said that the quadHD is the best
tuner by a long shot. After reading carefully the linuxtv.org page,
there appear to be kernel patches to use both tuners. Not sure I'll go
that route or wait for those patches to propagate into stretch-backports.

Strange. The lsusb -v output for the 026d device there says it's a 955D
in the iProduct field, mine only says "1", but the kernel message says
it's a 955D. Still, the usb ID points to needing kernel 4.11.

The firmware is for the 2040:0265, so no wonder it didn't do anything.
(/lib/firmware/dvb-demod-si2168-b40-01.fw). I had installed it from the
Thank you very much! At least now there's light at the end of the
tunnel. First, I'll see if the tuner is visible to kernel 4.11,
then I'll decide if I want to go the patch route or wait for the
2-tuner modifications to propagate to stretch-backports.
After that, I'll have to upgrade the myth machine (liva X) that is still
running jessie. I'm doing all this in a test machine for now.
