There's an experimental patch at http://people.freebsd.org/~iedowse/usb.diff that attempts to avoid the need for the USB subsystem to allocate any large contiguous chunks of memory. It would be useful if you could test this to see if it solves the issue. Recently I've updated the patch to try completing the OHCI support for non-contiguous allocations, so OHCI and in particular isochronous OHCI transfers may have problems. I'd be greatful if anyone could test the patch, especially with OHCI isochronous devices that currently work, since I've almost certainly broken something there. Ian
