AcerScan 620U - USB scanner not working

[abrazafi]

Hi,

Using 14.04 LTS (kernel 3.13.0-46-generic).
Tried to connect the Acer AcerScan 620U, through USB, without any success.
The device seems to be recognized by the system:

>scanimage -L
device `snapscan:libusb:004:003' is a Acer FlatbedScanner13 flatbed scanner

Then, when running skanlite, it says: Opening the selected scanner failed.

Any help would be appreciated and thanks,
Abdon.

You will need to copy a firmware file from the windows driver disk into a system folder and edit a config file for this.

Hi,

I followed the steps:
- I downloaded the U96V121.BIN file from www.nix.ru site
- I edited the /etc/sane.d/snapscan.conf file and added the following line

# Benq/Acer/Vuego 620U / 620UT
firmware /home/abdon/system/U96V121.BIN
usb 0x04a5 0x1a2a
usb 0x04a5 0x2040

When I typed the command

>scanimage -L
device `snapscan:libusb:004:003' is a Acer FlatbedScanner13 flatbed scanner

I rebooted the system and without success, still saying: Opening the selected scanner failed.

Please advise and thanks,
Abdon.

Looking at the /etc/sane.d/snapscan.conf file, I would suggest making it look like this:

#------------------------------ General -----------------------------------

# Change to the fully qualified filename of your firmware file, if
# firmware upload is needed by the scanner
firmware /usr/share/sane/snapscan/your-firmwarefile.bin <<I suggest placing the firmware here to be safe

# If not automatically found you may manually specify a device name.

# For USB scanners also specify bus=usb, e.g.
# /dev/usb/scanner0 bus=usb <<You might have to uncomment this line (remove the "#"
# For SCSI scanners specify the generic device, e.g. /dev/sg0 on Linux.
# /dev/sg0

#---------------------------------------------------------------------------
# No changes should be necessary below this line
#---------------------------------------------------------------------------

#-------------------------- SCSI scanners ----------------------------------
# These SCSI devices will be probed automatically
scsi AGFA * Scanner
scsi COLOR * Scanner
scsi Color * Scanner
scsi ACERPERI * Scanner

#--------------------------- USB scanners -----------------------------------
# These USB devices will be probed automatically
# (This will currently work only on Linux)

# Benq/Acer/Vuego 310U
usb 0x04a5 0x1a20
usb 0x04a5 0x1a26

# Benq/Acer/Vuego 320U
usb 0x04a5 0x2022

# Benq/Acer/Vuego 620U / 620UT
usb 0x04a5 0x1a2a
usb 0x04a5 0x2040

# Benq/Acer/Vuego 640U
usb 0x04a5 0x2060

<extra content snipped for brevity>

You might try finding the bin file in your windows system if possible. While that file on nix.ru is likely ok, you can't tell if it is good or not.
