It's worth noting that the reason legacy emulation causes problems is often that FreeBSD has not undone the BIOS's configuration of the EHCI controller. Adding 'device ehci' to the kernel config seems to fix this in many cases. What hardware were you seeing the problem on, and does it have an EHCI controller that's not being set up by FreeBSD? Many PCs these days have no PS/2 mouse or keyboard ports, so it's important that we work with legacy emulation turned on where possible. Ian
