The reason is not the USB stack; the reason (IIRC) is that the FreeBSD VM was written with the default assumption that Devices Never Go Away. A large rewrite, I'm told, will be needed to fix this, and the code is convoluted and tricky. No one finds the situation acceptable; introducing the "scapegoat" word isn't going to win you any support. The problem is not a weekend's worth of work to fix, nor does it have anything to do with avoidance by one particular maintainer, which you apparently had encountered before. mclhome | help
