extending usb cable mouse

[Simonnn]

I've got a Microsoft Optical mouse thats usb but goes through adapter into the mouse socket is it ps2 or something? I quite often watch films and episdoes on laptop when in bed and it would be really useful to control it from there and turn the comp off etc without getting up, I know you can get wireless but thats a bit more money, I was wondering if id experience problems If I brought a couple of meter usb extension cable, will there be anything with delay or loosing power, im not really too clued up on it all

thanks for any advice
