• get vendorid and productid by inspecting lsusb output.

  replace xxxx / yyyy with real id.

• add permission for wheel group (udev)

add file in /etc/udev/rules.d/, e.g. 90-betop.rules.

ATTRS{idVendor}=="xxxx", ATTRS{idProduct}=="yyyy", GROUP="wheel"

• reload rules manually (optional?)

# root
udevadm control --reload

• qemu cmdline option

... -usb -device usb-host,vendorid=0x{xxxx},productid=0x{yyyy} ...

fedora

package qemu-device-usb-host is required; otherwise device type usb-host will not be recognized.

bubblewrap

workaround with qemu-img (a fake usb img) and dd.
