I have a new usbuirt that I want to use as an IR transmitter/receiver
for mythbuntu 11.04. From a fresh boot, I do the following.
$ sudo /etc/init.d/lirc start
* Starting remote control daemon(s) : LIRC
R3 start-stop-daemon --start
--quiet --oknodo --exec /usr/sbin/lircd -- --output=/var/run/lirc/lircd

I modified the initscript to echo the start stop daemon commands. That is where
the R3 and R4 lines noted above came from. The init script claims it launched
OK, but notes that there was a problem. Before running the script, there was no
file under /var/run/lircd so I don't know why it has a problem with getting the
socket. Then irw failed to produce anything when I pushed buttons on the
remote, while I watch the LED on the uirt blink. I then ran mode2, which
verifies that LIRC is connected to the uirt device via USB and it's passing
bits to LIRC. My current understanding of problem is that the driver for
ttyUSB0 has changed and it doesn't communicate correctly with LIRC. The last
thing I did was to verify that my config files loaded correctly, with irsend
LIST. The haupauge note is the remote, the dish's are for transmitting to the
dish receiver. Thinking that perhaps the config files might be broken, I tried
making my own with once seemed to work, but typically fails on that error
message. I once got KEY_0 to come through as 00, KEY_1 as 01. Which worked, and
was much different than 0x0000000000001001 noted in lircd.conf.hauppauge.
I believe the key issue is that I need an updated config file, however I
can't create it with irrecord, as it appears that program fails because
of the checksum complaint.
Here's my hardware.conf file.

My /etc/lirc/lirc.conf has several comments, and one line
include "/usr/share/lirc/extras/transmitters/dish/general.conf"
According to synaptic
lirc (0.8.7-0ubuntu4.1)
mythbuntu-control-centre (0.63-0ubuntu1)
some syslog notes that might be of interest include

Also I expect to be using the driver usb_uirt_raw, not uirt2_raw which
is a valid driver, just not the expected driver.
I'm new to this bug reporting, so feel free to contact me at
launch...@jaredharvey.com for more information if there is something I
can do to help with resolving this problem.
