IPhone disabled and PC says USB Device not recognized?

I just charged my iPhone after a couple of weeks of it being at my dads to find it has been disabled (maybe someone tried to get in to it?).
Anyway, I plugged it into the PC I originally set it up on and each time I plug it in I get a popup saying that the usb device is not recognized.

Any help?

Added (1). EDIT: the iPhone is on -- it says I can try again in 22 million minutes haha
It's the fact that I can't plug it in to my laptop to sync with iTunes that is the problem because of the 'USB Device not recognized' message on my desktop when I plug it in.

Added (2). EDIT: I did the reset up to the point where it shows the image of an arrow between a USB and iTunes but the Device is still not recognized by my laptop.

Perhaps a problem with my usb cable?

How to convert IPhone GPS coordinates?

I'm looking at the geotag's from some old IPhone pictures and I can't convert them to the format Google maps wants. For example here is one reading from an IPhone picture:

38 21 6\'0" N
75 4 28\'0" W

But Google maps (or any others I tried) do not recognize it that way. Is there a way to convert this to their format?
