find-scanner: yes... scanimage: no


I posted in the Ubuntu forum regarding a problem with an HP Scanjet G4010 scanner, but now I have a specific question. The scanner is reported with lsusb and recognized by sane-find-scanner, but scanimage -L does not find the scanner.

My question is: What would be the cause of the scanner being reported in lsusb and sane-find-scanner but not recognized by scanimage -L?

TIA.

Does the scanner report it's name correctly?
Code:
scanimage --test
Are any errors reported?

See

Code:
man scanimage
for more info and a list of other utilities.

hello rl5,

it is essential as which user you executed the sane-find-scanner and the scanimage command. If both works for root but not for a normal user (or only sane-find-scanner for a normal user) you'll have to add the users to the adequate groups, e.g. the group scanner.

If scanimage -L doesn't even work for root you'll have to post more informations.

found USB scanner (vendor=0x03f0, product=0x4505, chip=GL845?) at libusb:004:002

The results are the same whether user or su... sane-find-scanner reports the scanner, scanimage -L doesn't.

Sane is 1.0.14-9

Well, please check if dbus is running.
Code:
ps -e | grep dbus

Well, I'd recommend to try "scanimage -L" instead, as root. If this is without a result, I think there is an issue with the driver. Have you used the scanner before with another distribution or with another version of Ubuntu or another kernel?

EDIT: Mh, doesn't look good http://www.sane-project.org/cgi-bin/...model=&bus=usb maybe your device isn't supported by Linux.

The results are the same - "sudo scanimage -L" does not find the scanner.

Not really - I've also tried it on Kubuntu 10.10 with the same results, but that's the same kernel. The scanner works fine with Win 7/XP.

Someone send me this link (scroll down to the bottom of the HP chart) so I had hopes I could get it working.

Well, this looks interesting.
Did the mentioned manpage for sane-genesys help you?
Check your system for the requirements in the manpage (e.g. libusb version higher than 0.1.6)
Edit the /etc/sane.d/genesys.conf file.
Check the mentioned environment variables.
Refering to that manpage I think there are chances to get it work.
Good luck.

Markus
