[sane-devel] Problem With Sane

[zoni]

I am have have a problem with sane. I am using Red Hat 9. I have Benq
3300. I copied the file u222v067.bin from my windows to /etc and made
the following changes as below. 


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

# Change to the fully qualified filename of your firmware file, if
# firmware upload is needed by the scanner

#firmware /etc/filename.bin
firmware /etc/u222v067.bin
# firmware /etc/u126v043.bin

# 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

# For SCSI scanners specify the generic device, e.g. /dev/sg0 on Linux.
# /dev/sg0





so know when I start the program, after 2 minutes it gives a message "
Failed to open device 'snapscane:/dev/usb/dcanner0':Error during Device
I/O"


after that I gave command and got following results, Please Guide Me.

  # SANE. Try scanimage -L and read the backend's manpage.

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).
