Actually, I'm arguing that you (FreeBSD, not necessarily the USB layer) need to better support the *main-stream* devices better (I care much less about the outliers, because by definition, the quality of their support affects far fewer people).

FreeBSD is a great system, superior to Linux in many ways that have been discussed ad nauseum, but USB devices, particularly disks and flash-based devices, are ubiquitous these days, and FreeBSD's support for these devices is weak, weaker than Linux and even OpenBSD (in my experience). This seems like a very odd place for a gaping hole in the system, particularly after all the work you did to re-implement the USB layer. /Don > > --HPS >
