I have the following error:

USB-hotplugging fails with "failed to load cgroup BPF prog: Operation not permitted" on cgroups v2
Hi all,
I've disabled cgroups v1 on my system with the kernel boot option
"systemd.unified_cgroup_hierarchy=1". Since doing so, USB hotplugging
fails to work, seemingly due to a permissions problem with BPF. Please
note that the technique I'm going to describe worked just fine for
hotplugging USB devices to running domains until this change.
