Please don't forget about this series. The new 8GB RPi4 contains this HW de=
sign
change and USB will not work without it. See this discussion on the downstr=
eam
kernel github, where other OS/bootloaders are hitting the issue:

https://github.com/raspberrypi/firmware/issues/1402

Otherwise, the Linux version of this is already in linux-next:
