As a slight aside to this, can't libxl use libusb for a lot of this
stuff and therefore avoid being Linux specific?

http://libusb.info/ claims to support "Linux, OS X, Windows, Windows CE,
Android, OpenBSD/NetBSD, Haiku.". Interestingly FreeBSD is missing there
but I don't think that need to be a blocker.

I don't see a problem with adding libusb to our set of dependencies, and
it's certainly got to be better than (re)implementing a bunch of sysfs
stuff (which I presume is what libusb does under the hood anyway).

Ian.
