[sane-devel] USB trouble - Fujitsu fi4120C

[Ed Greenberg]

I've got a Fujitsu fi-4120C hooked to an Ubuntu Natty system.

When I power the scanner on, I get

root at arthur:~# tail /var/log/syslog
Oct  7 17:11:51 arthur kernel: [15652.183350] usb 2-1.5: new full speed 
USB device using ehci_hcd and address 13

Then I do
root at arthur:~# scanimage -L
device `fujitsu:fi-4120Cdj:624506' is a FUJITSU fi-4120Cdj scanner

Then I do it again:
root at arthur:~# scanimage -L

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
root at arthur:~#



If I try to get a scan, I get

root at arthur:~# scanadf -d fujitsu:fi-4120Cdj:624506 --scan-script 
/usr/local/bin/mypnm2ps --resolution 150 --y-resolution 150 --mode Gray 
--source 'ADF Front'
scanadf: open of device fujitsu:fi-4120Cdj:624506 failed: Invalid argument

If I try a scan without the -d, I get

root at arthur:~# scanadf  --resolution 150 --y-resolution 150 --mode Gray 
--source 'ADF Front'scanadf: no SANE devices found

It's like the act of discovering it kills it.

I did all this as root to try and get permission errors out of the way.

Are there any suggestions?

Thanks, Ed
