Yet, cases like IR devices made by someone's own use is something that we don't need to care to have an in-kernel driver. > Personally I use LIRC exclusively for transmit to my settop box > using an old and obscure RECS80 protocol. > No, I won't replace my setup just because it's old and obscure. > > Cable companies tend to provide XMP based boxes to subscribers more often > these days. Simply not supporting these setups is a no-go for me. I don't see any reason why not supporting STB protocols. Several such hardware use Linux, anyway. So, eventually the STB manufacturers may send us decoders that work with their IR's. Cheers, Mauro.
