I think we may have some confusion here. There was some sort of EEPROM firmware upgrade [4] which I also did last round Raspbian was up (either Jan 11 or Feb 16). I also had to do that last year (August?) in order to make the RPI4 boot FreeBSD at all. I think the EEPROM upgrade tool is too Linuxish and does not run under FreeBSD (at least I failed).

I am aware of bug 252971 [5] and can confirm that I do have this version. Actually built on March 3 this year. Before that, I had to go back to some September? October? U-Boot to get the box back up running with USB (such as to use my USB keyboard & mouse, for instance).

I just connected a USB3 hub with a USB2 memstick and a USB3 disk to the USB3 hub of the RPI4, and both storage devices are detected immediately on either USB3 port of the RPI4.

Which gives me a sensation of looking in the wrong spot...

Thanks again, and

All the best,
