Well above all, user-space drivers can be of help in a lot of other ways. An example is rapid prototyping. Some times it makes sense as well to do in user-space, where you can really control things. Drivers using math is an example Manu - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
