I'd have hoped the SUN folks would know better than I would, but since they're being quiet I'll post my wild guesses.

I don't think the BIOS enters into the equation. I haven't ever played with SPARC at the hardware level, but in x86 you only need BIOS usb support to boot from USB -- not to use it in general. Once it boots the OS should have full, direct control of the USB controller.

If it doesn't, perhaps there's a way to make it so; if the USB ports are held by the BIOS for emulating old-style keyboards and mice can that be disabled? (but may be a bad, bad idea if it locks you out of any local console!)

There may be kernel drivers you need to load and so forth to get USB storage to work inside Sun systems, maybe device nodes to create if the system won't do it for you, etc.

EHCI(4)                                                    BSD Kernel Interfaces Manual                                                    EHCI(4)

NAME

     ehci -- USB Enhanced Host Controller driver

SYNOPSIS

     device ehci

DESCRIPTION

     The ehci driver provides support for the USB Enhanced Host Controller Interface, which is used by USB 2.0 controllers.

     EHCI controllers are peculiar in that they can only handle the USB 2.0 protocol.  This means that they normally have one or more companion
     controllers (i.e., ohci(4) or uhci(4)) handling USB 1.x devices.  Consequently each USB connector is electrically connected to two USB con-
     trollers.  The handling of this is totally automatic, but can be noticed since USB 1.x and USB 2.0 devices plugged in to the same connector
     appear to connect to different USB busses.

SEE ALSO

     ohci(4), uhci(4), usb(4)

HISTORY

     The ehci device driver first appeared in FreeBSD 5.1.

BUGS

     The driver is not finished and is quite buggy.

     There is currently no support for isochronous transfers.

BSD                                                               March 20, 2005                                                               BSD
