Works fine, I just have no need for it.

The USB-UIRT is a unique IR (infra red) receiver and transmitter. It connects to your computer through a USB port. It allows you to receive IR signals from regular IR remotes, like your TV remote. Together with a software package like Girder, the USB-UIRT allows your computer to be controlled by a remote in the house. 

On top of that since the USB-UIRT can send Infra Red signals as well it can control your normal Audio/Video equipment. This could be for example your DVD player, TV, Amplifier or Projector. Please note that this product is not compatible with all remotes and equipment. To determine whether it is compatible with your remote or equipment, please consult the Mp3Car Forums 

The USB-UIRT is a USB version of the now-notorious UIRT (stands for Universal Infrared Receiver Transmitter). The USB version offers a simple plug-and-play solution without having to deal with some of the hassles of the classic serial-port (RS-232) version. 

The USB-UIRT, along with Automation Software such as Girder [2] or StreetDeck, allows your PC to both Receive and Transmit infrared signals -- exactly like those used by the collection of remote controls you've acquired for your TV, VCR, Audio System, etc. The USB-UIRT can: - Receive signals from the remote controls you already have (allowing your PC to perform actions when the 'Play' button is pressed on your VCR remote, for example) - 'Learn' from remotes you already have and Transmit a duplicate of these signals from your PC (for example, your PC could automatically turn ON your VCR and tune it to channel 3) - Use codes available from the Web for other remotes (such as the Philips Pronto) to control all of your equipment with Remote (IR) receivers (including special 'discrete' remote codes your brand-name remote doesn't include!).
