Thanks for this posting.
I’ve got scanimage working, but for one hitch: each scan take a considerable amount of time to execute.
From what I gather the cause of the delay is not specifying --device, which causes scanimage to search for a locally available machine.
The obvious solution: specify --device.
That’s the curious part:
--device fujitsu doesn’t work, even though the device being used is a a Fujitsu iX500.
Error returned: "scanimage: *open of device fujitsu failed: Invalid argument*"
Running sudo scanimage -L returns fujitsu:ScanSnap iX500:[s/n] (where [s/n] is a partial serial number of the scanner)
Unfortunately, none of the following worked either…
--device 'fujitsu:ScanSnap iX500:[s/n]'
--device 'fujitsu:ScanSnap iX500'
--device 'fujitsu:ScanSnap'
--device 'fujitsu'
Question: How to properly specify --device for a Fujtsu iX500?
scanimage works if I leave out the --device option altogether, but each scan takes a long time to auto-discover the attached scanner.
