What is this in Device Maneger?

Its not Infrared Device bro cuz I have same thing in my Device maneger like you!

Thats only a little irDa port in our motherboard & we have to connect/install irda Device on that,then we can do whatever we want to do with infrared!

Its not a Device Bro! but a Port!

Yes, you do have an irda:

Short for Infrared Data Association, a group of device manufacturers that developed a standard for transmitting data via infrared light waves. Increasingly, computers and other devices (such as printers) come with IrDA ports. This enables you to transfer data from one device to another without any cables. For example, if both your laptop computer and printer have IrDA ports, you can simply put your computer in front of the printer and output a document, without needing to connect the two with a cable.

IrDA ports support roughly the same transmission rates as traditional parallel ports. The only restrictions on their use is that the two devices must be within a few feet of each other and there must be a clear line of sight between them.

http://www.foxconnchannel.com/product/Motherboards... shows under Internal I/O connectors that you have the IRDA.

According to their site your motherboard doesn't. Are you sure you, or someone else, didn't just install a program?
