im running xp not sure on model or year mind?, i plugged it in device manager came up but couldnt install it, the instructions are total shite to be fair, just say plug it in and no driver cd is supplie or needed apperently. its the original microsoft remote cant remeber where device manager is :$ , but there is no installation software so it has to be connected , even when not connected the drivers statte the same message . does the same on a similar pc set up downstairs. im not im afraid, does that involve changing the whole operating system??
