v-usb library and board type

I was trying some development with the v-usb library from rancidbacon.com and I noticed something odd. If I download the program onto my decimillia, it works ok, but trying to use it on an rbbb or an arduweenie, it does not work (and by not work, I mean that my syslog shows a usb device trying to connect, but it never gets any thing from it). The only thing I can think of is that the decimillia has a crystal and the other two boards use a resonator. Do any of yall have any experience with this? I would rather use one of my cheap boards for this.

I can program all three boards ok. The problem is that I'm trying to use the arduino itself as a usb device
