>Synopsis: [PATCH] Add quirk for uhid to ignore certain usb devices (blacklist)
>Severity: non-critical
>Priority: low
>Category: kern
>Class: change-request
>Release: FreeBSD 5.3-RELEASE-p10 i386
>Environment:
System: FreeBSD twind.austin.rr.com 5.3-RELEASE-p10 FreeBSD 5.3-RELEASE-p10 #3: Tue Apr 26 07:46:25 CDT 2005 root@xxxxxxxxxxxxxxxxxxx:/usr/src/sys/i386/compile/MINIME i386
<machine, os, target, libraries (multiple lines)>
>Description:
This patch allows uhid to leave alone devices that identify themselves as hid based, but are indeed
used via another interface. This is very simliar in concept to the hid blacklist table found in hid-core.c
in the linux kernel.
<precise description of the problem (multiple lines)>
>How-To-Repeat:
Applies to 5.3/FreeBSD-CURRENT kernel. Runtime tested.

>Fix:
<how to correct or work around the problem, if known (multiple lines)>
