To make this work, the phone would need an irda stack and the kernel drivers for 
the usb dongle. I would be very surprised if there are phones with those 
features enabled. Most phones don't even have the more common usb-serial 
drivers. So the chance that this will work out of the box is probably near zero.

In theory you could implement a userspace stack (there is a java implementation, 
which is also being used by Scubapro's Logtrak application) in combination with 
a userspace usb driver.
