A failure leading to mount root failure:

All 3 got:

usbd_req_re_enumerate: addr=5, set address failed! (USB_ERR_IOERROR, ignored)

as the first failure of the sequence.

This establishes that U-Boot is not the only thing to
have problems with your equipment.

I'll note that the:

da0: <SABRENT  0214> Fixed Direct Access SPC-4 SCSI device
da0: Serial Number DD564198838F9

does not match other log files:

da0: <SABRENT  1214> Fixed Direct Access SPC-4 SCSI device
da0: Serial Number 000000000000A

but it may well be an example of garbage-in/garbage-out.

The same goes for the usual:

umass0:  SCSI over Bulk-Only; quirks = 0x8100

vs. the 3 odd examples:

umass0:  SCSI over Bulk-Only; quirks = 0xc105
umass0:  SCSI over Bulk-Only; quirks = 0xc105
umass0:  SCSI over Bulk-Only; quirks = 0x8101



You also got another "0 Storage Device(s) found". It again has
the sequence for portstatus:

311, 311, (sequence of 5 instanced of:) 301

for:

Manufacturer 
Product      U-Boot Root Hub
SerialNumber 
bind node usb1@1

So, just like the others.
