I should have stated that the driver was likely still loaded as I simply
used "uparrow" to recall the previous command which was still onscreen
and in the history buffer... I tried this a couple of times with no
luck. Then, I power-cycled the scanner and tried again, then thinking
"Nuts!", I got the idea to load xcdroast to check the status of the SCSI
bus/devices. When I retried the command, it now worked...
I posted this to point out that there may be a recovery glitch in the
code on certain errors or conditions.
BTW, both LEDs on the scanner were off during the first try (before the
power-cycling).
HTH,
