I have no idea why this has happened but for those who have the same issue here it is.

while updating to ios 7 iTunes was unable to identify my phone. I thought I was bricked. even after going into dfu mode. no luck. iTunes comtinues to wait for iPhone to be plugged in. after some research and a bit of freakout mode.... I discovered that apple moble usb drivers for windows 8 were not installed. installed them by letting windows search my computer for them and boom fixed.

good luck
