Hi all,
I implemented a simple project for testing the V-USB driver with atmega64 and works fine with windows xp, but windows 7 64 bit doesn't detect the hardware and produce the " usb device not recognized " error.
Is there anyone that has checked the V-USB with windows 7 64 bit?
what is my mistake?

Yes it work fine, nothing is needed for changes. Check out USBLyzer (free trial) to see what the issue is. If you are using mega168/328/88 make sure you use 1/4 z-diodes.
