A Kubuntu kernel on a Debian 11 host? I can at least confirm it works fine using the stock Debian 11 kernel (5.10.113-1 from bullseye-security) with packages built using the documented dpkg-buildpackage -b -uc -tc command.

@estatistics So Kubuntu virtual machine on Debian 11 host, right? Perhaps you didn't have kernel-headers installed on a target system (Debian 11). On my Debian 11 kernel module installed properly:

$ lsb_release -a

So you can try:

cd vhba-module
make
sudo make install
cat /etc/group | grep cdrom
sudo reboot
sudo lsmod | grep vhba
# I have /lib/udev/rules.d/70-uaccess.rules already, so (check INSTALL file instructions):
sudo echo "KERNEL=="vhba_ctl", MODE="0660", OWNER="root", GROUP="cdrom"" > /lib/udev/rules.d/40-vhba.rules
# Then make it autoloadable:
sudo echo "vhba" > /etc/modules-load.d/vhba.conf

As @boltronics mentioned dpkg-buildpackage -b -uc -tc command can help you to see unmet dependencies. In my case I had an cmake error during libmirage build:

$ cd libmirage
$ mkdir build
$ cd build
$ cmake ..

brought me a message with packages to install:

sudo apt install libsamplerate0-dev gtk-doc-tools gobject-introspection libgirepository1.0-dev intltool

You can also install cdemu packages without build from deb-multimedia:

sudo gpg --no-default-keyring --keyring /usr/share/keyrings/deb-multimedia.gpg --keyserver keyserver.ubuntu.com --recv-keys 5C808C2B65558117
echo "deb [signed-by=/usr/share/keyrings/deb-multimedia.gpg] \
https://www.deb-multimedia.org $(lsb_release -sc) main non-free" \
| sudo tee /etc/apt/sources.list.d/deb-multimedia.list
sudo apt update
apt install vhba-dkms cdemu-client cdemu-daemon gcdemu

But both ways (building from sources and install from packages) you could add systemd unit if you wish to enable autostart of cdemu-daemon:

# cat /.config/systemd/user/cdemu-daemon.service

[Unit]
Description=cdemu-daemon

[Service]
Type=simple
ExecStart=/usr/bin/cdemu-daemon
StandardOutput=syslog
StandardError=syslog
TimeoutStartSec=0

[Install]
WantedBy=default.target

then:

systemctl --user daemon-reload
systemctl --user enable cdemu-daemon --now

Hope it helps now.
