No - it won't work. It *MUST* be a real serial port since if you look at
the wiring it uses either the RTS or DTR output control lines and the lirc
driver waggles them 40,000 times a seconds with great accuracy. You just
can't do that with a USB stack.

I hope the serial blaster was less than $2 as thats how much they cost...
