USB-UIRT Broken in karmic

[andrew1056]

I originally bought the usb uirt for linuxmce, but switched over to mythtv. It was working at receiving and transmitting until the karmic upgrade.

As a receiver I was using the devinput kernel module which is no longer found; however, there is no entry in /dev/input/event* for it. When lirc starts it no longer creates lirc0 which is what I was using for the receiver device previously.

The problem is I can get it to both receive and transmit, but never at the same time. It's either one or the other.

I can transmit when both are enabled, but not receive. If I try to run irw the errors in dmesg are this (I can still transmit fine though):

The WAF has gone way down and I don't know if it's my config because somethings changed or something in lirc is broken.

Here's hardware.conf

# /etc/lirc/hardware.conf
#
#Chosen Remote Control
REMOTE="Hauppauge_350"
REMOTE_MODULES=""
REMOTE_DRIVER="uirt2_raw"
REMOTE_DEVICE="/dev/ttyUSB0" // used to be /dev/lirc0 but it's not created anymore
REMOTE_LIRCD_CONF="hauppauge/lircd.conf.hauppauge"
REMOTE_LIRCD_ARGS=""

#Chosen IR Transmitter
TRANSMITTER="SAE8000"
TRANSMITTER_MODULES=""
TRANSMITTER_DRIVER="uirt2_raw"
TRANSMITTER_DEVICE="/dev/lircd1"
TRANSMITTER_LIRCD_CONF="scientificatlanta/general.conf"
TRANSMITTER_LIRCD_ARGS=""

#Enable lircd
START_LIRCD="true"

#Don't start lircmd even if there seems to be a good config file
#START_LIRCMD="false"

#Try to load appropriate kernel modules
LOAD_MODULES="true"

# Default configuration files for your hardware if any
LIRCMD_CONF=""

#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"
FORCE_NONINTERACTIVE_RECONFIGURATION="false"
START_LIRCMD=""
REMOTE_SOCKET=""
TRANSMITTER_SOCKET=""

lircd.conf just includes the hauppauge remote and the scientific atlanta box.

Part of this is a broken /etc/init.d/lirc script (which I'm planning to
patch today).  I don't know if that's related to your segfaults though.
