I just connected my Genius Vivid-1200TA scanner to my laptop USB port, now how use it?
In windows, there was a software and driver available for the device. The software has many good features to use the scanner. But I do not know how to use it in Ubuntu 14.04?
gscan2pdf obtainable free from the Ubuntu Software Centre or simple scan are often good starting points for using scanners under Ubuntu 'straight from the box' without the need to download additional drivers.
I use xsane, which is intuitive and required no additional drivers (for my scanner; your mileage may vary).
