oh, a dumb USB unit! interesting. Though I'm not sure of the exact
support level we'll have with HAL. But it gives me more visibility,
and that's a good point. thanks.

I'm interested in...

even more friendly than its competitors I would say ;-)
and not only linux, but also our *bsd and solaris cousins too...

testing and reporting is a good contrib for me, since I only own MGE
(and maybe soon APC?!)

thanks again,
