USB-PS/2 to Bluetooth hub? Such a thing?

[patrickvp]

Hello! New to the forum and new to Bluetooth.

I'm setting up a home theater with PC access, and the PC itself will be about 40 feet away from the theater in one of the other rooms. A friend recommended using Bluetooth for mouse and keyboard control in the theater, so I don't have to run USB though the house.

My question is this: Are there any products out there that act as a sort of USB-to-Bluetooth hub? Basically, I'd rather not have to deal with batteries for the mouse and keyboard, and would rather "plug them into something" for power, but then let Bluetooth handle the actual talking to the computer. I've heard that gaming wireless mice can really burn through batteries...
