Subject: PATCH: allow ide-generic users to ask it to capture unknown devices
Date: Fri, 05 Nov 2004 16:22:18 +0000 [thread overview]
Message-ID: <1099671737.5556.32.camel@localhost.localdomain> (raw)
Most of this patch is neccessary noise to make the generic entry "id 0" so
that the code is clean and won't need touching each time an identifier is
aded.
