JMicron jms561 umass on arm64?

Thank you, Mark,

I apologize for not having been precise in my elaborations. I now understand that

Power-on of the RPI
  loads EEPROM
    loads Firmware          rpi-firmware-1.20210303.g20210303
      loads U-Boot          u-boot-rpi4-2020.10 (config.txt says kernel=u-boot.bin)
        loads "FreeBSD"     [3]

And each of them may or may not be able to properly provide access to USB. In any case, FreeBSD [3] does start, and does detect USB devices, so I'm happy this far.

Returning to my initial issue, what puzzles me is that I do not seem to be able to see the hat [2] at all while
(a) Raspbian did see it (and the disks, so I understand that the hat is in order),
(b) There are reports that the JMS561 [1] should be detected also by FreeBSD, and
(c) FreeBSD does detect any other USB device I I can find and hook up to either one of the USB3 ports (indicating that the RPI is fine).

In short, my expectation (hope?) was that I hook up the board and proceed with the disks, or at least be able to re-set the bus so that it finds at least a ugen device to build upon, but as-is, no trace of any device... I'm a bit lost and would appreciate any pointers.

Thanks again, and

All the best,

Peter.
