WinTV HVR-1950 USB2
« on: February 25, 2009, 01:22:57 am »
BACKGROUND

I read someone was able to get the Hauppauge WinTV-HVR-1950 external USB2 analog and digital tuner working with MythTV and LMCE. I believe they got it working with the existing PVR-USB2 drivers. I have read all the problems with internal PCI/PCIe cards and lack of support for new chipsets, etc. like the HVR-2250. It seems like it is easier to support if the interface is USB and all that changed is messages.

QUESTIONS

Is the HVR-1950 planned for official support soon?
Is there anything that I can do to help test/develop since I have the hardware?

What needs to be done is a device template needs to be made for the device. The WinTV PVR-USB2 device template can be used as a pattern. Just being sure to substitute the vendor/model ID appropriately, and maybe using the same setup scripts as for the WinTV PVR USB2.

I also read somewhere in addition to having the PVRUSB2 kernel support enabled or compile the kernel module, that you must download and compile some sort of firmware interface from the Windows drivers.   

Also, if you can post a link or two to get me started looking into the "device template." 

I attached the output of the lsusb -v command listing the device information.

Well, you can look here, this page was started, but not finished:

http://wiki.linuxmce.org/index.php/Edit_Device_Template

The best way to learn is to look at an existing templae. You can ask me questions and I will attempt to answer them.

OK I did confirm that you do in fact need to extract the firmware from the windows drivers. 

1. Read instructions for downloading the firmware extraction tool.

2. Insert the driver CD or download the latest firmware from the hauppauge site.
http://www.hauppauge.com/site/support/support_hvr1950.html
3. ./fwextract.pl {cd or folder path}/Drivers/
4. cp *.fw /lib/firmware/

Still don't have the HVR-1950 working with mythtv yet, but will post progress....
