So I have a card that I think has a PCI ID to be 1745:2100.  Or 1043:4889 not such which
It’s a ViXS Systems card (ASUSTek)
Any idea if it’s supported?
All my searching tends to say its not but all those answers are from 2012 and in 6 years I would hope some progress was made.
link to any threads describing chips inside?
I don’t have any
what answers did you find from 2012? 
That LinuxTV will never support this card because there is no documentation on it. 
I would hope someone would have been able to make progress towards it.
chibill: somehow i must have missed the earlier part of the conversation, but im just curious as to what device you speak of?
