>>> Salut Fabien!

>>> Tried your gb.scanner component today :)

>>> It would not work, it failed with 'unable to load image'.

>>> Then I found the Debug option, and it gave me this in the Gambas konsole:
>>> scanimage --device-name=smfp:usb;04e8;3413;8J21BAJYA08601M. --mode=Color
>>> --resolution=300 -p --format=tiff > /tmp/gambas.1000/6888/1.tmp
>>>
>>> When I pasted this in the linux terminal, scanlite says:
>>> scanimage: open of device smfp:usb failed: Invalid argument
>>> bash: 04e8: command not found
>>> bash: 3413: command not found
>>> bash: 8J21BAJYA08601M.: command not found
>>>
>>> I then tried to do this:
>>> scanimage --device-name='smfp:usb;04e8;3413;8J21BAJYA08601M.' --mode=Color
>>> --resolution=300 -p --format=tiff > /tmp/gambas.1000/6888/1.tmp
>>>
>>> Then scanlite says:
>>> scanimage: setting of option --mode failed (Invalid argument)
>>>
>>> Finally, this worked:
>>> scanimage --device-name='smfp:usb;04e8;3413;8J21BAJYA08601M.'
>>> --resolution=300 -p --format=tiff > /tmp/gambas.1000/6629/1.tmp
