Thanks, Bob,

Sorry about that. My main box just broke and is in repair and the bl**min' web GUI set HTML on *every single* message I send. I hope to have found a permanent knob now, though. The stupid Aw: in the subject line, and not reducing to a single Re: also is really embarrasing but there seems to be no knob for that... sigh! Not used to consumer UIs any more.

> usb reset

That cuts the branch I currently sit on (USB, HDMI). And does not show anything ... but an error (gone now, rpi4 continues to boot when I pull the keyboard off to type this). I'd love to boot (e. g. bootcmd_usb0) from the disks but to do that, I'd have to get them on-line first, I guess...

I also noted earlier, that, in my current setup, upon the first boot after power-up, I have no means to interfere with the boot process at all until FreeBSD was up at least once. Subsequent 'warm' reboots do give me access to the boot prompts (u-boot, FreeBSD loaders).

I also was hoping that, once BSD's taking over, USB would be reset, all devices found, etc. ... but looks like life's not that easy. I'll dig further into U-Boot now as the root cause seems to live there...

I have an RPI48GB with the current indicated below [3].

Thanks again, and

All the best,

Peter.

G'day, folks,

Is there, by chance, anyone out there who has a JMicron jms561-based USB3 'umass' kind of device up & running who can share experience or quirks, please?

I'm trying to get mine [2] to work under FreeBSD [3] but it does not even show up with usbconfig list. While, with Raspbian, I was able to make it work easily.

Thanks,

Peter.
