[Mauro <1184699@xxxxxxxxxxxxxxxxxx>]

In Linux Mint 17 (Ubuntu 14.04) the situation is much worse: I can't ever scan. With Mint 16 (Ubuntu 13.10) the "invalid argument" error message just happened sometimes, now it happens almost always. 
With Skanlite, it's either shown almost immediately, after a weak movement, when pressing the preview button, or after the backlight has moved from top to bottom, without returning the actual preview result. 
With XSane the situation is the same, with the only difference that when the error is not given immediately, the scanner backlight runs fast from top to bottom and then hits against the bottom of the plate, while the motor keeps on trying to move it even further (the scanner makes very bad noise, I have to unplug the USB cable otherwise I fear it will get damaged).

In other words, support for this scanner is severely broken in the latest release and I think it may even damage the hardware :-(
Is there a hope that it will get fixed?

Bug description:
