[mythtv-users] Can't get ir-blaster working with mceusb and using ir-keytable for the remote

Wed Apr 3 16:12:14 UTC 2013

I'm in dire need of  help getting an mceusb ir blaster to work properly
for use with mythtv.  I know there is a lot of expertise on lirc for
mythtv here, I hope it's not too off topic.

It's probably some minor issue, but I've been beating my head against
the wall for a good week now, and just not getting anywhere. This is for
my daughter's production mythtv (working remotely just makes it more
challenging). 

Although she had been patient with her dad, I'm loosing all my geek
creds here.  I'm also not totally a newbie, I've been using and setting
up mythtv for about 5-6 years now. Always with an mce blaster.

Here is the issue in a nutshell:  I have the remote working
(ir-keytable), but can't get the ir blaster to work using mceusb.  When
I use irsend it acts like it worked, but no ir signal comes out the
other end.  

I've read other posts that indicate it should work (including one from
Jarod I believe), but no luck for me.

I'd greatly appreciate any insight you can give me, and if anyone has a
working hardware.conf and lircd.conf using ir-keytable for sending and
mceusb as an ir-blaster, that would also be very helpful.

Thanks in advance!

Mythtv devs, you guys are great!  What a fantastic bit of coding magic!!

Here are the results of irsend:

irsend --device=/var/run/lirc/lircd1 SEND_ONCE SAE8000 8

results in lircd -n
$ sudo /etc/init.d/lirc start 
* Starting remote control daemon(s) : LIRC
[ OK ] 
lircd-0.9.0[4120]: lircd(default) ready, using /var/run/lirc/lircd1

lircd-0.9.0[4120]: accepted new client on /var/run/lirc/lircd1
lircd-0.9.0[4120]: removed client

But, no results (red light, channel change) on the ir-blaster.

Here is the set up and system information.  If any other information
would be helpful, I'd be glad to provide it.
