[mythtv-users] USB dual channel IR blaster?

I'm starting to gather parts to put together a new backend machine.
One issue I'm having is figuring out what to do for IR blasters.  I
need to be able to control two identical set-top-boxes, and they only
understand one set of IR codes, so I need two independently
addressable IR blasters.  My current setup uses a couple of serial
blasters with two instances of the related kernel modules and lirc
daemons.  I'd keep using that kind of set up, except that it seems
that modern-ish motherboards only have one serial port anymore.

I have a usb-based MCE remote (this one:
http://www.newegg.com/Product/Product.aspx?Item=N82E16880121002)
currently hooked up to a frontend.  The receiver part works great, but
I can't get either of the two blaster parts to do anything.  It shows
up in the syslog as a "Topseed Technology Corp. eHome Infrared
Transceiver"

Does anyone have an example of a usb-based transceiver where both
blasters actually work?  I guess the other option is a PCIe serial
port add on card.
