Visioneer OneTouch 9020 scanner not working

SharpyWarpy · #1 7th February 2011, 07:42 PM

Hi, all. I got a Visioneer One Touch 9020 USB scanner at a local thrift store and I can't get it working. At the store they said it works. Not tested with Linux. It was only $3 so I figured I'd take the plunge -- proceeds go to local charities. Running sane-find-scanner outputs this:
# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.

# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a kernel SCSI driver for your SCSI adapter.

I put a line in /etc/sane.d/dll.conf:
visioneer
And created the file /etc/sane.d/visioneer.conf with this line:
usb 0x04a7 0x022c
But when I run Xsane it says "No Scanners Found". A little Googling says this scanner is supported. Anybody know of a special module I need to modprobe? Any help at all is greatly appreciated.
UPDATE:
I found out the genesys.conf file in /etc/sane.d is the correct config file to add the line
usb 0x04a7 0x022c
so I did that and deleted the "visioneer.conf" file. But I still can't get sane to find the device. Running the command
scanimage -L
says no sane devices found, as does the Xsane program when I try to start that. Should I take apart the scanner and see what chip it uses?
On a side note, the same thrift store has a Mustek scanner that has only a USB connection, apparently drawing power from the USB bus. But I'm skeptical about this because all the scanners I've seen require 1.25 amps of current and USB provides only 0.5 amps. Has anyone any experience with this scanner and would it be worthwhile to purchase it and try to get it going? I have two scanners that work well with Linux but they are both the multifunction type that copy, scan and print. I'm hoping I can find a regular flatbed scanner. And I should also mention I have Python-imaging-sane installed for flatbed scanners.

Here's an update, of sorts.
The Visioneer 9020 flatbed scanner is not supported. Just for kicks and giggles I tore it down and it has a Lexmark processor chip. Imagine that. I despise Lexmark devices. Not only because they are a pain with Linux. They are not reliable with Windows either. But that's another subject.
I went back to the thrift store and got another scanner, a Mustek 1200 UB. It works fine. All I had to do was uncomment the line Mustek_usb in /etc/sane.d/dll.conf. There's only one cord, the USB cord. Since it gets it's power from the USB bus it needs to be connected directly to a port on the computer, no hubs. At least unpowered ones. All this was an interesting, enlightening venture and I hope sharing it will help someone in the future.
