Flutterby™! : Aaaargh!

It's been a hellish several days, but I now kind of have a handle on cross-compiling Linux for this ARM platform I'm dealing with. At this point, two things still frustrate me:

1. buildroot still seems to be creating my modules with a different version magic string than my kernel.
2. I haven't figured out why libusb isn't seeing the USB devices that my kernel is loading, and, by extension, why this isn't getting forwarded to BusyBox for hot-plug management.
