I just bought a Microsoft Wireless Notebook Optical Mouse and I'm afraid to take it out of the package just in case this won't work (I doubt the retailer will accept a return once it's been used). The package says "USB only" but I'd like to use my regular PS/2 mouse port since I use the USB port for other things. If I use one of those USB to PS/2 adaptors, will the mouse still work? I did this with another corded Microsoft optical mouse that I bought but it came with the adaptor.
