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.
