The "eHome Infrared Transceiver" aka "MCEUSB" devices work quite well.
And as of 2.6.36, have an in-kernel driver, no more out-of-tree lirc
driver. Several other usb-based transceivers exist, but none are as
simple to get working, nor as inexpensive.

Not sure if the blaster part on those works under Linux yet.

Oh. That 2250 actually comes with an MCEUSB device, its not an onboard
IR blaster. You can buy the MCEUSB transceiver (with remote)
stand-alone for $25-30 from newegg.
