[root@localhost tmp]# scanimage -L
device `hpaio:/usb/Photosmart_C3100_series?serial=CN6ARC321S04KV' is a Hewlett-Packard Photosmart_C3100_series all-in-one
That agrees with the output from hp-scan, but it does not seem to help.
What permissions do I change?
root@localhost tmp]# find /dev -name 'Photo*'
[root@localhost tmp]# find /usb -name 'Photo*'
find: `/usb': No such file or directory
[root@localhost tmp]# locate Photosmart_C3100
[root@localhost tmp]#
I used strace on hp-scan.
It used every "file" under /dev/bus/usb:
[root@localhost tmp]# ls -R /dev/bus/usb
/dev/bus/usb:
001 002 003 004 005
/dev/bus/usb/001:
001 006
/dev/bus/usb/002:
001
/dev/bus/usb/003:
001 002
/dev/bus/usb/004:
001
/dev/bus/usb/005:
001
[root@localhost tmp]#
For some reason, hp-scan also opened a lot of sane libraries,
mostly for brands other than HP.
hp-scan read "Photosmart C3180\n" a lot.
