Hi,
I have a Hauppauge HVR-2210 tv tuner card that is not currently
supported by V4L saa7164 driver.
The card is recognised but is reported as unsupported
CORE saa7164[0]: subsystem: 0070:8953, board: Unknown
[card=0,autodetected]
I found some support for this subsystem in what I assume to be a old
dev tree at
http://kernellabs.com/hg/~stoth/saa7164-dev/
So perhaps it was something lost in porting saa7164 module to the v4l
tree, or perhaps there was some issue, I couldn't work out the history
around this.
I have used that code (without any understanding of it) to patch the
saa7164 driver as below, and this has been successful - I have been
using the card with MythTV happily for about a month now.
So my question is how do I ask developers to consider including support
for this card in future releases ?
This is my first time reaching out to the Linux community and I am
merely a Linux enthusiast/user (not a programmer) - so apologies if I
have taken the wrong tact for such a request.
Appreciate any help.
Jason
Two patch files I use ...
