My problem came with the clean reinstall of mythbuntu using a Terratec Cinergy DT USB.
Everything works fine except the remote control support.
I used my previously working hardware.conf / lircd.conf and .lircrc files.
irw gives no feedback when lirc is running. Regenerating the lircd.conf file with irrecord failed as it showed no response to keypresses and quit with "gap not found" after a few seconds. So my guess was a flaw with the hardware.conf file (below).
However the remotes arrow keys and numpad work even if lirc is not runnin!
So i have absolutely no clue what is wrong.
device paths are confirmed to be correct.
Is the kernel based IR support somewhat overriding lirc?!
#Chosen Remote Control
REMOTE="Terratec Cinergy DT USB XS Diversity"
#Chosen IR Transmitter
#Don't start lircmd even if there seems to be a good config file
#Try to load appropriate kernel modules
# Default configuration files for your hardware if any
#Forcing noninteractive reconfiguration
#If lirc is to be reconfigured by an external application
#that doesn't have a debconf frontend available, the noninteractive
#frontend can be invoked and set to parse REMOTE and TRANSMITTER
#It will then populate all other variables without any user input
#If you would like to configure lirc via standard methods, be sure
#to leave this set to "false"
Any help is greatly appreciated!
