I've managed to run into this article [1] that explains that even if you have all permissions and no SELinux you can still be blocked by something called kernel_lockdown and it should appear in dmesg.

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. Attaching / detaching USB devices
