Hauppauge HVR 1950 USB

Help & Support Hardware
1

I have a Hauppauge HVR 1950 USB that doesn’t get installed to /dev/dvb during boot with CE19 but it is fine with LE10. Does the CE kernel support pvrusb?

Have you tried to install crazycat or latest kernel driver’s modules? You’ll find them at addons->services. After installation you’ll find a module selector in the addon’s tab at home page.

Yes I tied both of them but still get unsupported device. That is why I thought it might be pvrusb2 related

not supported, sorry.

Is it a v4l thing with Amlogic or is there a way to manually rebuild the kernel to enable it?

# Analog TV USB devices

# CONFIG_VIDEO_PVRUSB2 is not set

I am sorry to disappoint you but we currently don’t have the resources to support DVB. In fact maybe with the next major CE 20 release we might drop all drivers not supported by the then used Kernel which will be newer than 4.9.

8

I understand and fortunately the driver I want is in the kernel. I just was hoping to be able to enable another kernel config option to build CoreElec myself.

9

The info we found is that it requires a more recent kernel than 4.9. Correct us if we are wrong.

10

My primary Debian Buster backend is running 4.19 and I see it is there

/usr/lib/modules/4.19.0-17-amd64/kernel/drivers/media/usb/pvrusb2/pvrusb2.ko

If I install Armbian N2 Buster with the 4.9 kernel would that tell you the information you need?

I just wanna know where this comes from. I use Debian for my system myself but 4.19 is quite not near 4.9 if you can understand. There are worlds between them.

12

Really sorry I wasn’t thinking, I thought it was 4.1.9 pvrusb is very old though I find references back to kernel 2.6.18

In any case would testing with Armbian 4.9 give any clarity?

13

Internally we discussed it and it seemed I misunderstood and 4.9 kernel is supported. No idea it that works.

14

@emveepee please have a try with this test image:

no idea if it will work…

15

Thanks for that it does need pvrusb

Unfortunately it faults http://ix.io/3uqH so don’t spend a lot of time on it. I tried the 3 all sets of firmware.

Yes, I think without the hardware in the hand it would not be possible to solve the issue. There are some few commits on this driver in mainline kernel what one maybe solve it. Maybe when the new kernel will come up someday it start working.

Case closed
