I have had similar problems with my iguana usb ir transceiver on an older tv. I had to use a usb repeater on that tv or hold the device really close. Maybe its just not strong enough?
Not all IR LED's have the same frequency range, a repeater could fix this problem as well. Kind of a stupid solution but it had worked for me in the past.

Hey Guys,

I bought a USB IRBLASTER from irblaster.info.  It uses the
FT232RL chip.  I was abe to get ir working with the ftdi
driver accessing it with
  lircd --driver=nameofblaster --output=/dev/lircd /etc/lircd.conf

with the above and using irsend I was able to see the blaster
flash.  So I am getting information through LIRC and out  through
the actual blaster.  The output in the LIRCD is

 hwftdi_send() carrier=38000Hz f_sample=524288Hz

I see the flash... but the channel does not change on the STB.

I also have a serial blaster that uses lirc_serial to work.  It
works fine and I am using the same lircd.conf file for both.

Are there any parameters such as baud rate or anything else that
I can use to make this work?  The output parameter is set to 2
by default.  Is that the correct one?

I saw there was a different note that mentioned the use of the
mplay2 driver.  I tried that one but LIRCD locked up and there
was no flashing on the IRBLASTER.

It would be great to be able to nail this down since I very few
of my systems actually have serial ports now a days.

Any help would be greatly appreciated as this is pretty cool
software and I would love to get the USB versions running!
