Firstly, sorry for the slow response here...

I now have what appears to be lircd correctly running and monitoring my
two devices:

# ps aux | grep lirc
root      5411  0.0  0.0      0     0 ?        S    19:46   0:00 [lirc_dev]
root      5440  0.0  0.0   3848   556 ?        Ss   19:46   0:00
/usr/sbin/lircd -d /dev/lirc0 --output=/dev/lircd --listen
root      6316  0.0  0.0   5940   644 ?        Ss   19:49   0:00
/usr/sbin/lircd -d /dev/lirc1 --output=/dev/lircd1 --connect=localhost
8765 --pidfile=/var/run/lircd2.pid


Still no luck with my irsend though, see below for more details...

I'm using the 250. AFAIK, it does not include built in IR blasting. I do
have a serial IR blaster... I've removed the pvr150 module:

s# lsmod | grep lirclirc_serial            16160  0
lirc_i2c               13316  2
lirc_dev               18504  2 lirc_serial,lirc_i2c

cx88xx,bttv,lirc_i2c,i2c_ec,msp3400,saa7115,tuner,nvidia,i2c_viapro,ivtv,i2c_algo_bit,tveeprom


My setup is Hauppauge remote -> Hauppauge receiver, serial IR blaster ->
sat box. The transmitting is what is not working now, receiving is fine.

I've done so, reconfigured the lirc_serial module, and now I'm seeing
the following at startup:

# dmesg | grep serial
[   18.700461] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[   32.229127] tveeprom 0-0050: Hauppauge model 32062, rev C199, serial#
8552356
[   49.343566] lirc_serial: auto-detected active high receiver

This is the error I'm still getting...

For some reason the startup script is not starting up the second
instance on its own... I'm doing that manually for now.


Thanks for all your help and patience!
