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.

The config file for the Xorg version of the X Window System is /etc/X11/xorg.conf. The log file for the Xorg version of the X Window System is /var/log/Xorg.0.log (or similar).
Where are your X log files located?
# 3  
The X log files are located in /var/X11/Xserver/logs/. A long listing of the directory looks like this:

-rw-rw-rw- 1 daemon daemon 3313 Nov 8 16:12 X0.log
-rw-r--r-- 1 root daemon 138 Nov 8 16:12 Xstartup.0.log

Again, no error info appears in either of the logs. The X0.log even contains the entry "Fri Jul 5 14:47:58 2019: /usr/lib/X11/extensions/hp7lc2k.1" conveying that the added lines to /etc/X11/X0devices resulted in the hp7lc2k.1 driver being loaded but the USB barcode reader not work together with the keyboard.
