It occurred to me earlier today to look for firmware files.  I'm pretty
sure I looked before but this time, thanks to the ubuntu repository I
added previously, I found this:

i linux-firmware-hauppauge                     0.1.0+zesty    0.1.0+zesty

which I promptly installed.

I'm trying not to install a whole ubuntu kernel.  If I can make it work
by installing firmware or drivers I'd prefer that.  Unfortunately, this
firmware doesn't seem to do anything, or the kernel/system doesn't know
what to do with it.

I also manually loaded pvrusb2, the driver that the old usb tuner used,
but that too didn't make any difference.  IIRC, this driver got loaded
automatically when the old tuner (OnAir Creator) was plugged in.

I wonder if this is not the correct firmware file for this tuner.  The
firmware file installed is:

/lib/firmware/dvb-demod-si2168-b40-01.fw

I think I'll call Hauppauge tomorrow.

That's what I would have thought.  This is what shows up in
/var/log/messages when plugging it in:

kernel: [435914.697341] usb 1-6: new high-speed USB device number 3 using ehci-pci

No mention of missing firmware files like I've seen in other cases.

Thanks for taking the time to reply.  I'll keep trying.  Any other hints
or advice most welcome.
