Hi there!
this year for a school project i decided to try and make a multi touch screen using LEDs as photo diodes. i started playing around with some LED matrices, ADCs and a basic stamp (im alright programming a basic stamp) but then stumbled upon this interesting project:

it was essentially exactly what i wanted to do and the creator had put all the eagle files and source code on the internet.
using the his documents, i had the pcb manufactured and ordered all the parts from digikey then assembled it all and tested most of the connections, joints etc to make sure everything was put together correctly.
i plugged it in an the little blue LED on the board flashes for a short bust (receiving usb data from the computer) then my computer tells me that the USB device is not recognized.
i know i need to download some software and drivers but i have absolutely no idea where to start.
ive had a look over the atmel website but i’m still clueless…
any help would REALLY be appreciated
