Thank you for the confirmation.


STFW:

https://www.asrock.com/microsite/DeskMini/#Specification

It appears that platform supports Intel processors with integrated graphics:

CPU 	Supports 7th and 6th Generation Intel® Core™ 
i7/i5/i3/Pentium®/Celeron® Processors (Socket 1151) (Max. TDP 65W)


I have seen the keyboard and mouse issues on the following hardware:

1.  Dell Inspiron E1505, Intel Core 2 Duo T7400 processor, Intel GM 945 
chipset (Intel® 82945GM Graphics and Memory Controller).  I believe 
Debian uses the xserver-xorg-video-intel driver.

2.  Dell Latitude E6520, Intel Core i7-2720QM processor, Optimus 
graphics (Intel HD Graphics 3000 and NVIDIA NVS 4200M discrete 
graphics).  I typically disable Optimus in the CMOS setup, which 
disables the Intel graphics.  Debian uses the nouveau driver.

3.  Desktop with Intel DQ67SW motherboard, Intel i7-2600S processor with 
Intel HD Graphics 2000.  I believe Debian uses the 
xserver-xorg-video-intel driver.

My WAG is that a bug was introduced in the X Windows and/or desktop 
drivers 1~2 years ago on Debian 9, 10, and 11.

Please let us know if you make any progress.
