my ipod touch is stuck with an I tunes logo and a usb chord with an arrow pointing to the logo. What is this and how do I fix it?

My Ipod is stuck with a picture of a USB chord with an arrow pointing to an itunes logo....what is this and how do I fix it? I did look at the "printers and devices" section on my computer. It shows an un identified "apple" device that is in "recovery mode" but that is. I tried to trouble shoot it there but no help....
