I've searched for some kind of explanation for this in the man pages,
to no avail. Can anyone suggest why scanimage thinks my scanner is
busy?
[root@home /root]# scanimage -V
scanimage (sane-backends) 1.0.4
[root@home /root]# scanimage -d coolscan:/dev/scanner
scanimage: open of device coolscan:/dev/scanner failed: Device busy
[root@home /root]# cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 02 Lun: 00

[root@home /root]# ./sane-backends-1.0.4/tools/find-scanner
# Note that find-scanner will find any scanner that is connected
# to a SCSI bus. It will even find scanners that are not supported
# at all by SANE. It won't find a scanner that is connected to a
# parallel, USB or other non-SCSI port.

And here is the output of strace. I have no idea why it is looking
for the v4linux devices.
