Touchpad module bricked with v12.3.3

[nader-eloshaiker]

UHK 60 v2 with touchpad module and firmware v12.2.0

• Performed firmware update to v12.3.3 and latest agent.
• firmware failed (output below)
• keyboard works and touchpad works but getting ERR on LCD display and agent cannot find keyboard.
• remove touchpad and cycle power on keyboard and ERR goes away. Agent also recognises keyboard again.
• Installed touchpad module and ERR appears again but agent continues to work. Restarting agent fails to find keyboard.
• Attempted to unbrink by shorting the two pads and running fix device had no effect, with and without the touchpad module.
• Attempted to re-install firmware with and without module also did not fix it. (I did this by removing the module, launching agent and then plugging the module in).
• Right clicking on flashfirmware does not show recover touchpad, only shows trackpoint and trackball. This is with and without module connected.

Sorry for the bug. The #2529 PR fixes it. We will merge and release it soon

Fixed by UltimateHackingKeyboard/firmware#1128

Please upgrade to firmware 12.3.4 without the touchpad module attached. Afterward, firmware updates should work regardless of whether the touchpad module is connected.
