I *think* that you might not be able to use lirc with a USB to serial
adapter.  I recently had an IR project to do, and this is the first
route that I took since my laptop had no serial port.  However, after
much flailing, I found the following quote on the lirc.org website:

(http://lirc.org/faq.html)
"""
Can I use a home-brew LIRC receiver with a Serial to USB adapter?

No, this won't work. But there is a project working on a dedicated USB
transceiver <http://tusb3210.sourceforge.net>. Using an Irman with USB
adapter should work though.

"""

I ended up using a PCMCIA serial adapter with a home-brew, then moving
to an Irtrans (http://www.irtrans.de/en/).  They have a great lircd
interface, and I did not even have to change my lirc client calls.

Hope this helps,
