Configure X windows with both keyboard and USB barcode reader

Greetings.
Seeking guidance on adding a USB barcode reader (BCR) to an HP c3750 workstation with HP-UX 11.11 which is essentially configuring X windows to accept input from both a primary keyboard and a secondary keyboard that happens to be the BCR.

Historically, I have successfully added a BCR to an HP c3600 workstation with HP-UX 10.20 and a c3700 with HP-UX 11.11 by configuring X windows to accept input from both a primary keyboard and a secondary keyboard as stated above by adding the following lines to /etc/X11/X0devices :

Code:

Begin_Device_Description
Name    hp7lc2k.1               # USB Barcode reader driver name
Use     Other                   # This is an "Other" device
Path    /dev/hid/kbd_001        # Second keyboard device file
End_Device_Description

However, this does not work for the c3750. Adding the above lines to /etc/X11/X0devices does not appear to have any discernible effect on configuring X windows to accept input from two keyboards. A review of X windows generated logs shows no errors. X windows behaves as if no modifications where made to X0devices. The c3750 accepts input from either the primary keyboard or the BCR but not both.

kbdmux

KBDMUX(4)						   BSD Kernel Interfaces Manual 						 KBDMUX(4)

NAME

     kbdmux -- keyboard multiplexer

SYNOPSIS

     device kbdmux

     In /boot/device.hints:
     hint.kbdmux.0.disabled="1"

DESCRIPTION

     The kbdmux keyboard driver provides support for basic keyboard multiplexing.  It is built around the idea of a ``super keyboard''.  The
     kbdmux driver acts as a master keyboard consuming input from all slave keyboards attached to it.

     Slave keyboards can be attached to or detached from the kbdmux keyboard driver with the kbdcontrol(1) utility.

SEE ALSO

     kbdcontrol(1), atkbd(4), syscons(4), ukbd(4)

CAVEATS

     The kbdmux keyboard driver switches all slave keyboards into K_RAW mode.  Thus all slave keyboards attached to the kbdmux keyboard share the
     same state.  The kbdmux keyboard is logically equivalent to one keyboard with lots of duplicated keys.

HISTORY

     The kbdmux module was implemented in FreeBSD 6.0.
