 I've updated rpi-firmware to 20210303 now that they've taggued it, usb
works on my RPI4. This will not be in 13.0-RC1 as the builds have
already started I think but this will be in the RC2 image.
 If anyone wants to follow progress at
https://github.com/raspberrypi/firmware please do and open reviews if
you want to update the port in the futur.

 Cheers,
