Yes! It is also not *that* intrusive as it may sound at first look: basically we need a central registry that collects all the identification data (vid,pid,strings and what have you) plus the parent and the device pointer, and a flag if this is a device claimed by some driver or one of the currently visible ugen* things. Due to this being USB we already have detach support everywhere, and only need a bit of additional glue. Martin
