For the USB host functionality a supported host controller is required,
currently it is only MAX3421E. The example can be built as follows:
.. zephyr-app-commands::
:zephyr-app: samples/subsys/usb/shell
:board: nrf52840dk_nrf52840
:shield: sparkfun_max3421e
:gen-args: -DCONFIG_UHC_DRIVER=y -DCONFIG_USB_HOST_STACK=y
:goals: flash
:compact:
It is theoretically possible to build USB support using virtual USB controllers
for all platforms, eventually the devicetree overlay has to be adjusted slightly if
the platform has already defined or not `zephyr_uhc0` or `zephyr_udc0` nodelabels.
