/* $NetBSD: uvisor.c,v 1.9 2001/01/23 14:04:14 augustss Exp $ */
/* $FreeBSD$ */
/* This version of uvisor is heavily based upon the version in NetBSD
* but is missing the following patches:
*
* 1.10 needed? connect a ucom to each of the uvisor ports
* 1.11 needed ucom has an "info" attach message - use it
* 1.12 not needed rcsids
* 1.13 already merged extra arg to usbd_do_request_flags
* 1.14 needed sony and palm support
