I don't think the support for loading the USB firmware on the 8Gb
model has made it upstream yet. In the 1/2/4gb models it was loaded by
the Raspberry Pi firmware from SPI flash, in the 8Gb model they
dropped the SPI flash and there has to be kernel patches to load it.
That problem is unrelated to the CMA/DMA issue.
the USB quirk is available in Linux 5.8 [1], but there is a related
report [2].
It seems to be related to the board revision and possibly arm64.
A dmesg output might be helpful.
