They don't only work on Linux. They also work on BSDs, and MacOS X (at least). It's what libgphoto2 uses, and I believe it works on much more than just Linux. > I know they're used elsewhere (gphoto), but this > is just not the right thing to add to OpenOBEX. > > HOWEVER, > libusb 1.0 has just been released.

Is that ok? I'd rather fix the discovery properly so we can avoid all the kind of problems we'd get from using only what's currently exported from openobex. The only problem I'd see with the patch is that it probably breaks ABI...
