!!! Setup of Acer/BENQ USB Scanner:
----

__System:__

Ubuntu 6.06

__Kernel:__
> Describe [ScannerHowto] here.


2.6.15-28-686


__Scanner:__

* Flatbed Scanner, 600 x 1200dpi (Windows?), USB 1.0, labeled as 'Vuego 4300U'.
* Power pack is: 16VDC @ 1A; Center terminal on plug is Positive (+)/Outer terminal is Negative (-).

----

!! Search for Scanners that are loaded/recognised:


Run tail on /var/log/messages.


* 'tail -f /var/log/messages'


Scanner gets recognised when plugged in:

(The output of my 'Tail' command):

* "usb 5-2: new full speed USB device using uhci_hcd and address 2"



! Do:

'lsusb'.

This gave me:


* 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












! Do:

* 'cat /proc/bus/usb/devices'.


See if the scanner was recognised and loaded a driver - look for something after the "Driver=xxx" bit - in my case, none was found (this section is redundant when using 2.6.x kernels???).


My output is below (other USB devices were there as well, I just didn't list these as they are irrelevant):



* 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

! See what xsane has to say about the state of things:

Open terminal window, as _normal user_:

Run 'xsane'.

(If not installed, 'apt-get install xsane' as root on CLI, or via Synaptic)



I received a GUI error message from xsane:


* "Error: Failed to open device 'snapscan:libusb:005:002': Invalid argument"




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


Close GUI error message.

! Configuring snapscan:



Note CLI message from xsane:


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


In CLI (any user), 'cd /usr/share/sane/snapscan'


* "bash: cd: /usr/share/sane/snapscan: No such file or directory"


... it doesn't work, because the directory isn't there.




Lets make it.

As root user (CLI):

* 'mkdir /usr/share/sane/snapscan'



Change to your snapscan directory:

In CLI (root user)

* 'cd /usr/share/sane/snapscan'

----

! Locating firmware:

Now we need to find (on the internet) the firmware for your scanner:


Open Device Manager (System==>Administration)


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"
and
* "usb_device.vendor_id"



Mine looks like:


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




We need to find firmware (maybe!) that needs to be uploaded? to the scanner before it will work?


Do a google search, or look on snapscan.sourceforge.net for the product_id/vendor_id (e.g. '0x20b0' and/or 0x4a5').



On sourceforge, I found:


* "Acer / Benq 3300 / 4300 USB 0x04a5, 0x20b0 "FlatbedScanner23" u176v046.bin"

So I need to locate firmware "u176v046.bin".


I found this located inside the windows driver files for the scanner.

I copied this firmware into "/usr/share/sane/snapscan".

I did a (as root) 'chmod -R 777 /usr/share/sane/snapscan' - may be a security risk!!!


Edit your /etc/sane.d/snapscan.conf:

As root user:

* 'gedit /etc/sane.d/snapscan.conf'

Alter to suit your binary firmware file.

Save.

----

! See what we did:

Run 'xsane' as normal user!

You should see "Waiting 20 seconds, scanner warming up".

Wait a bit, and Xsane should fire up!

w00t!! :-)

! Notes to self (Author) for page improvements:

* 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 :-)
