lirc + serial irblaster:hardware does not support sending

[matttah]

I have a happauge pvr 350 with an IR reciever that is working fine. However I recently got an IR blaster(http://irblaster.info/) which I cannot get to work with lirc. I have modprobed the lirc_serial and setup /etc/serial.conf with:

Code: Select all

/dev/ttyS0 uart none       

However when I run

Code: Select all

$: irsend send_once DC50X 2
irsend: command failed: send_once DC50X 2
irsend: hardware does not support sending

I've also tried specifying the device to irsend with-d /dev/lircd1

Any ideas what I am doing wrong?

I realize this is an old thread, but matttah describes the same problem I'm having now. There are a few other threads that describe the same symptom but offer no viable solutions.
I have:

Code: Select all

server ~ # dmesg| grep -i lirc 
[    8.422738] lirc_dev: IR Remote Control driver registered, major 61 
[    9.361235] lirc_serial: auto-detected active high receiver

Code: Select all

And error:

Code: Select all

server ~ # irsend SEND_ONCE Toshiba_CT-90287-TV power
irsend: command failed: SEND_ONCE Toshiba_CT-90287-TV power
irsend: hardware does not support sending

I have the IR Blaster from http://irblaster.info I bought via Google Checkout.
Has anyone who has experienced this old problem found a solution?

(On a side note, this is my first post to f.g.o. in years! Tried Arch for a while but ultimately things didn't work out and I'm baaaack!)
