Those dev nodes' owner group is vboxusers, which you can add your user to. However, qemu does not use those. As you can see, dev nodes under /dev/bus/usb/, which qemu uses, has the owner group of root. You will need to either set the permission for "others" to rw (it's just r now, as you can see), or add an ACL entry for it (like what uaccess in a udev rule would result in). | |

| Jun 22, 2024 at 15:18 | comment | added | Tom Yan | Why do you have -usb between the host controller and the passthrough'd device? Also, what's the permission of the device /dev/bus/usb/xxx/xxx (assuming you are not running qemu as root)? | |
