mythdora lirc problems, remote+serial blaster

I'm running Mythdora 12.23 with a Hauppauge 250 and am having trouble with
both the Hauppauge remote and a serial blaster. The reciever is the one
that plugs into the back of the Hauppauge card and the blaster is a
homebuilt LED+resistor+diode from the Lirc page.

When I first installed the system, and used the Mythdora IR devices
configuration tool to set up just the remote, it worked fine. Later when I
used the configuration tool to add the blaster, the remote stopped working
and the blaster never worked. I chose the option that said
"serial/IguannaWorks IR Blaster(COM1)". Since I didn't make any manual
changes outside of the config tool I'm assuming that the tool messed up
the settings.

I've followed the various troubleshooting sources that I can find, but
many of them are old or are for MythBuntu, which seems to have a different
configuration. I'm hoping someone can see the problem from what I've
posted here or can walk me through the correct troubleshooting steps.

I know the light is flashing on the Hauppauge remote but I can't get any
output from irw. When I add the channel change script to Myth I get error
messages in the backend log that say:

irsend: command failed: SEND_ONCE Pace_RC-30 6
irsend: hardware does not support sending
irsend: command failed: SEND_ONCE Pace_RC-30 6
irsend: hardware does not support sending
irsend: command failed: SEND_ONCE Pace_RC-30 OK
irsend: hardware does not support sending

Note that my remote is actually the Pace DC50X but that's not listed in
the configuration tool. I figured I would worry about the actual remote
type later after I got the blaster light to flash.

Here are the results of some of the troubleshooting commands I have found.
Let me know what other info I can provide.

The IguanaWorks IR Blaster is a different device from a homebrew
serial device, so that's likely at least one reason why its not
working. lircd is trying to talk to an IguanaWorks device, which uses
a userspace driver, instead of using the "default" driver (connect to
a /dev/lircX device that has a kernelspace driver).

Yep, that's not unexpected, given the device type mismatch.

In the IR Devices config tool my only choices are:

No IR Blaster
Serial/IguanaWorks IR Blaster (COM1)
Serial/IguanaWorks IR Blaster (COM2)
PVR-150 IR Reciever/Blaster
MCE-USB IR Blaster
CommandIR Mini
CommandIR II
USB-UIRT IR Blaster

By the way, running the config tool the remove the blaster and go back to
only the Hauppauge remote doesn't make the remote work again.

Hrm. Perhaps I'm wrong, and the IguanaWorks serial blasters use
lirc_serial. Its certainly not any of the other options there. What
does /etc/sysconfig/lirc look like? And /etc/lirc/lircd.conf?

Based on your dmesg output, its at /dev/lirc1, and lircd by default
expects it at /dev/lirc0 (which is the device lirc_serial is bound
to). Multi-device is... messy, even if you fully understand how all
the parts are wired together. Point lircd at /dev/lirc1 instead, and
the remote should work again (look for the device setting in
/etc/sysconfig/lirc), but beware that if you change module load order
between lirc_i2c and lirc_serial, they'll flip-flop.

Completely empty? Or just nothing added to any of the config options
in there? Empty in either case means lircd using /dev/lirc0 and the
"default" driver (i.e., attach to a kernel device), which given that
you've got lirc_serial loading first, means lircd is trying to talk to
your transmitter. However, if I'm remembering clearly (btw, while
trimming replies is appreciated, its also possible to trim too much
from a reply...), you were getting a message about the device not
supporting transmit. Not quite sure what to suggest right now. I'd
probably reverse the load order though, so lirc_i2c loads first, then
the remote should at least work. I'm really not all that familiar with
the auto-config stuff in mythdora myself, not sure how the blaster
setup is supposed to have come out.

Should only have one or the other, not both. Not sure which one takes
precedence.
