As said before, please reconsider this decision in the light of the
quick disappearance of `repos/dde_linux/src/drivers/usb_host`.

It is set in the platform driver's devices ROM, e.g. in
`genode-imx/board/imx6q_sabrelite/devices`. Moreover, you have to
assign the devices to your driver within the platform driver's policy.
For an example, have a look at:
`genode-imx/repos/imx/recipes/raw/test_usb_host_drv-imx6q_sabrelite/drivers.config`
