For some time now I've been booting an Rpi3B+ using a microSD
card configured with
U-Boot 2019.10 (Mar 17 2020 - 22:01:14 -0700)
by stopping it at the u-boot prompt and issuing
usb reset
followed by
run bootcmd_usb0
after which the usb hard disk boots and all is well.
Lately, usb reset has taken to reporting
resetting USB...
Bus usb@7e980000: scanning bus usb@7e980000 for devices... Device NOT ready
Request Sense returned 02 04 01
5 USB Device(s) found
scanning usb for storage devices... 0 Storage Device(s) found
However, usb tree reports
USB device tree:
1 Hub (480 Mb/s, 0mA)
| U-Boot Root Hub
|
+-2 Hub (480 Mb/s, 2mA)
|
+-3 Vendor specific (12 Mb/s, 90mA)
| FTDI FT232R USB UART AM00FGTR
|
+-4 Vendor specific (480 Mb/s, 2mA)

+-5 Mass Storage (480 Mb/s, 0mA)
ASMT ASM105x 12345678D558
The problem isn't wholly new; the usb reset command sometimes had
to be repeated once or twice before the disk was found. Now it seems
a persistent failure.
Once FreeBSD has booted, the disk is seen and accessed as usual.
Thanks for reading, any hints appreciated!
