In order for my HDMI/USB KVM switch to work with my Logitech K400+ keyboard and trackpad, I have needed to blacklist the hid_logitech_dj kernel module. With bullseye, I have done this by putting a file containing
blacklist hid_logitech_dj
in the /etc/modprobe.d/ directory.
This is now ineffective. When the system boots, the hid_logitech_dj module is loaded, despite it appearing in the blacklist list, and my keyboard and trackpad don't work (unless plugged in directly, without the switch) until I ssh into the system and do a "modprobe -r hid_logitech_dj". Then, my keyboard and trackpad work. Obviously, I would like the blacklist to actually work, and prevent loading the hid_logitech_dj module.
