Something tells me that if you were to enable USB Legacy Support and run Linux or Windows, you'd have a functioning mouse. This could simply be a BIOS bug (would not surprise me), or (more likely) a bug in FreeBSD's initialisation of the USB chip. FreeBSD's USB stack is under a great amount of (justified) scrutiny as of late, and there are efforts under CURRENT to replace the stack with a complete brand-new written-from-the ground-up stack (patches are available). It would be beneficial if someone with this sort of configuration oddity could run CURRENT with the new USB stack patches applied and see if things behave as expected. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
