You can find the galaxy note drivers on the US Samsung site (and only this one). I unfortunately cannot post the direct link as this is my first post...
If, like me, your Galaxy Note is not recognized by your PC with a "driver not found" message, try to look in your device manager.
I had for some reason a Bluetooth device that was not correctly recognized (yellow "!"). I uninstalled the Bluetooth device (which I never used anyway) and suprisingly when I plugged my Galaxy Note back it was perfectly recognized this time.
Hope this helps!
