Thanks for the help! But will this take me all the way?

Maybe I misunderstand something but this will only ensure that I always
have the same symlink names? What I also think is needed is for the
Hauppauge card to also load the correct IR driver.

Comparing the two IR receivers only one have a driver loaded.

Driver: (null), table: rc-dib0700-rc
Driver: em28xx, table: rc-pinnacle-pctv-hd
