The 1.1 USB IR device will not work. You DO have to get the USB 2.0 IRda device.
The only old style device that I was able to use was the SERIAL device, connected through a Keyspan USB to Serial adapter.
The new Polar USB 2.0 IRda device is MUCH better. Greater communication range, faster downloads, no stalls.
You do need to download and install the Polar driver if you are using Win98 or Win2k. After the driver is installed, the USB 2.0 IRda device will show up on the USB list as "STIr 42XX"
Win98 and Win2k drivers here:

No drivers needed for Vista. The drivers for the STIR4210/15/20 are built-in to Vista on both the 32-bit and 64-bit platforms.
