Fujitsu fi-7160 SANE Problem

[diogo8]

Hi

I'm trying to scan a document with my Fujitsu fi-7160 using the SANE library (1.0.25) but i'm having some problems.
First of all when i run the command 'sudo scanimage -L' it only find the scanner at the second try, strange right? But that isn't bothering me at all.

The main problem is when i type 'sudo scanimage --test' or some command with scanimage and any options. The scanner reacts and moves the paper very quickly.
When i look at the terminal this is the result:

(...)

And i don't get any output file. I think that the bold lines are responsible for this malfunction.
I've tried to change the buffer size but the result is the same. I've tried also with diferent versions of the SANE library but nothing changes. This weekend i'll try with another scan models.
I really need to put this working and i would be very appreciated if you could help me here.

Thank you.

I have updates

Some linux guru told me that USB 3.0 ports may be unstable using the SANE library.
So i plugged the cable in the only usb 2.0 port (the gray one, not the blue ones).
With this change i got different results, this time the scanner doesn't react when i execute the scanimage command and the result of the log is this:
