Actually, NetBSD has had the UMS_BUT() macro this way since the beginning (revision 1.16), it wasn't changed by the uhidev commit. I have no idea what's the correct thing to do here, what's quite sure is that one of us has it wrong :-). You should send a mail to [EMAIL PROTECTED] since he changed the UMS_BUT() macro this way a long time ago when committing patches from Nick Hibma : revision 1.16 date: 1998/12/26 12:53:03; author: augustss; state: Exp; lines: +439-88 Merge changes to make the USB stack work with FreeBSD. The original diffs from Nick Hibma <[EMAIL PROTECTED]>, but with substantial changes from me. XXX Not tested on FreeBSD yet.
