My current kernels will block ADB writes when the bus is still
beeing reset/probed. So pmud should work. However, I had some
reports of pmud just screwing up the trackpad in this case, which
may be related to a bug in an older release of pmud. One problem
is that I think debian did some updates to it, but the maintainer
did't update the official version. Well, I might have just missed
something here as I use to rely on debian's version :)
