How To: AT91 SAM7 - USB-driver for CDC with Win7 and XP..

This article want's to show all interested users how to connect your SAM7 device as a "CDC" to Windows XP and Windows 7. This is the missing part for the Atmel "at91lib" and examples using connection with the newer operating systems 32/64bit like Windows 7.

All you need is to modify the Vendor ID, Product ID and the corresponding strings like descriptions.

Let' make a blank file with your texteditor and paste the following text. It works fine for the Windows versions above. Feel free to test it with Windows Vista (i haven't this version). Have fun!
