USB devices undetectable

Each time I would connect a USB device it would pop up with options to do something with it.
So I figured I would turn it off because I didn't want the menus to constantly keep popping up every time I connect a USB device, but now it's not detecting the devices period.
I didn't think it would not detect the USB devices at all; the menu that pops up to prompt you to either, burn CD, open folder etc. that menu.
Does anybody know how I can re-enable the ability to use the USB devices when connected without the popup, but also without deeming them unusable either?

What you did before you, change the setting back to how it used to be.

And about the menu, disable autorun and autoplay

The easiest way is to goto Windows button on the bottom left click Computer tab on the options to see whether the device(s) is/are there or detected by Windows or else undo what you did last time. It could be the device is faulty.
