Nook Color with CyanogenMod7 is not visible via ADB over USB
I finally tracked down a fix after some file searching...

The "adb over usb" fix creates a file in %USERPROFILE%\.Android\adb_usb.ini with the "vendor id" of 0x2080 in it.

I have a .android folder in my root of my sdk directory c:\android-sdk\.android\, and in there is also the adb_usb.ini. I added the 0x2080 to that file, then restarted adb and I can now see the device via USB->adb.
