1st: Do you have any android phone? This is the best way to check that your pc with android sdk is properly configured. Once you are able connect to a phone, you can be sure that the problem is on the nook site
2nd: Let me tell you the way how I have rooted my nook and made usb work (because I have decided not to use touchnooter). I used noogie image to get rw access to nook partitions and replace uRamdisk on nook with the uRamdisk attached here:
Of course, backup the original one.
On linux site, it was also necessary to add udev rules (as mentioned on the page) but this is linux related. I can't help with windows, for me they are too difficult to use :)
But I can confirm that mentioned uRamdisk works.
