System:
    Ubuntu 6.06
Kernel:
    2.6.15-28-686
Scanner:
    “Vuego 4300U”

    * Flatbed Scanner
    * 600 x 1200dpi (Windows?)
    * USB 1.0
    * Power pack 16VDC @ 1A
    * Center terminal on plug is Positive (+)/Outer terminal is Negative (-).

!!! Procedure:

# __Before plugging in__: <tt>tail -f /var/log/messages</tt>

# __When the scanner is recognised__ upon plugging it in, the following message appears:

  <verbatim>
  usb 5-2: new full speed USB device using uhci_hcd and address 2
  </verbatim>

# __<tt>lsusb</tt>__

  Output:

  <verbatim>
  Bus 005 Device 001: ID 0000:0000
  Bus 001 Device 001: ID 0000:0000
  Bus 003 Device 001: ID 0000:0000
  Bus 002 Device 001: ID 0000:0000
  Bus 004 Device 002: ID 04a5:20b0 Acer Peripherals Inc. (now BenQ Corp.) S2W 3300U/4300U
  Bus 004 Device 001: ID 0000:0000
  </verbatim>

# __Check <tt>/proc/bus/usb/devices</tt> to see if the scanner was recognised and loaded a driver__ – look for something after the "<tt>Driver=xxx</tt>" bit. None found in my case:

  <verbatim>
  T:  Bus=05 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#=  2 Spd=12  MxCh= 0
  D:  Ver= 1.00 Cls=ff(vend.) Sub=ff Prot=ff MxPS= 8 #Cfgs=  1
  P:  Vendor=04a5 ProdID=20b0 Rev= 1.00
  S:  Manufacturer=Color
  S:  Product= FlatbedScanner 22
  C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr=100mA
  I:  If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none)
  E:  Ad=81(I) Atr=02(Bulk) MxPS=  64 Ivl=0ms
  E:  Ad=02(O) Atr=02(Bulk) MxPS=   8 Ivl=0ms
  E:  Ad=83(I) Atr=03(Int.) MxPS=   8 Ivl=16ms
  </verbatim>

  (This section is redundant when using 2.6.x kernels???)

# As normal user, __run <tt>xsane</tt> from a TerminalEmulator to see what it has to say__.

  <verbatim>
  Error: Failed to open device 'snapscan:libusb:005:002': Invalid argument
  </verbatim>

  Note the numbers '5-2' from the [tail(1)] command, and also the '005:002' from xsane... this looks promising.

# __Running snapscan from a TerminalEmulator__:

  <verbatim>
  [snapscan] Cannot open firmware file /usr/share/sane/snapscan/your-firmwarefile.bin.
  [snapscan] Edit the firmware file entry in snapscan.conf.
  </verbatim>

  That directory does not even exist and it certainly doesn't contain a file called <tt>your-firmwarefile.bin</tt>, so...

# __Let's find the firmware for the scanner__. Open ''System'' → ''Administration'' → ''Device Manager'', scroll down/expand the tabs to the devices with names similar to:

  * "xxxxx (xxxx Family) USB UHCI"
  * "xxxxx (xxxx Family) USB2 EHCI"

  Look for a device that has names/numbers/model/etc. associated with your scanner.

  E.g. mine has "S2W 3300U/4300U" under "82801G (ICH7 Family) USB UHCI #4" tab.

  Click on that device, and then in the right pane, click on 'Advanced', which shows heaps of stuff.

  Look for the two lines that have the following:

  * "usb_device.product_id"
  * "usb_device.vendor_id"

  Mine looks like:

  * "usb_device.product_id int 8368 (0x20b0)"
  * "usb_device.vendor_id int 1189 (0x4a5)"

  Do a Google search, or look on http://snapscan.sourceforge.net/ for the product_id/vendor_id (e.g. '0x20b0' and/or 0x4a5'). I found ''Acer / Benq 3300 / 4300 USB 0x04a5, 0x20b0 "FlatbedScanner23" u176v046.bin''.

  I found <tt>u176v046.bin</tt> inside the MicrosoftWindows DeviceDriver files for the scanner.

# __Put the firmware in the right place__:

  <verbatim>
  mkdir /usr/share/sane/snapscan
  cp u176v046.bin /usr/share/sane/snapscan
  chmod -R a=r,a+X,u+w /usr/share/sane/snapscan
  </verbatim>

  Now edit <tt>/etc/sane.d/snapscan.conf</tt> to point the configuration at your binary firmware file.

# As a normal user, run <tt>xsane</tt>. __This should now work__.

!!! Page TODO

* Ensure each part is in the correct order, e.g. loading firmware we haven't located yet, etc. (sanity check? :-) )

  * Check USB is configured OK
  * Identify Scanner
  * Check to see if Scanner is recognised by USB system
  * Identify/locate/download firmware for scanner
  * Install firmware file(s)
  * Configure snapscan? to upload firmware
  * See if Scanner is recognised and loads
  * Test if scanner works
  * Ensure scanner works the same through a cold boot of PC and scanner !

* Space things out more - looks too cluttered

* Remove irrelevant/obsolete commands

* Add more links

* Learn how to do Wiki pages better, so __others__ can understand them!!!

* If this To-Do list is still here, feel free to pester the Author :-)
