how to add sosumi to virt manager in manjaro

I,ve installed sosumi on manjaro. I'm new to Linux. After installing I tried to connect USB devices. But sosumi is not responding to it. So I searched the web to find a solution. But tried so many solutions. Even uninstalled sosumi and installed Big Sur with usb passthrough codes. Tried to add qemu kvm to virt manager. But none of it worked on my Manjaro. I need help.
