[Bug 508704] [NEW] Benq s2w 3300u does not work with sane (I/O error)

[Xan]

Public bug reported:

My problem is that I have benq szw 3300 u scanner. According to snapscan
page [http://snapscan.sourceforge.net/], I have to download u176v046.bin
or u222v067.bin windows firmware and put it in /usr/share/sane/snapscan.
Then I have to edit /etc/sane.d/snapscan.conf.

I did it, and only I get that the scanner warms up. But no scan images.
When I run scanimage, I receive the error:

scanimage: open of device snapscan:libusb:002:002 failed: Error during
device I/O

Any suggestions?
Perhaps it's a bad firmware?

Thanks a lot,
Xan.

PS: My snapscan.conf is like:

# Change to the fully qualified filename of your firmware file, if
# firmware upload is needed by the scanner
firmware /usr/share/sane/snapscan/u176v046.bin
[...]

# Change to the fully qualified filename of your firmware file, if
# firmware upload is needed by the scanner
firmware /usr/share/sane/snapscan/u176v046.bin
[...]
