OK, I have now tried that. The command line I used was
./setup_sdcard.sh --mmc /dev/sdb --dtb beaglebone
--bbb-old-bootloader-in-emmc
the problem remains. I tested this several times and I did see (once) the
BBB appear as a USB drive on the remote PC. In that instance the BBB did
reboot successfully. However after rebooting and again plugging in the USB
cable, the error appeared, the BBB would not mount as a USB drive and the
SD card was rendered unbootable.
I have found an error message reported by the remote Linux PC. This appears
to be output by the process which is trying to mount up the BBB as a drive
over USB:
Error mounting /dev/sdb at /media/dtree/rootfs: Command-line `mount -t
"ext4" -o "uhelper=udisks2,nodev,nosuid" "/dev/sdb" "/media/dtree/rootfs"'
exited with non-zero exit status 32: mount: wrong fs type, bad option, bad
superblock on /dev/sdb,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
