HP ScanJet 5370c freeze after first scan

Detailed description
Hi,

My HP ScanJet 5370C works fine for the first scan but it is frozen after and I have to power off/on it to work again.

I've attached two files resulting from :

% SANE_DEBUG_AVISION=255 scanimage 2>debug >image
% SANE_DEBUG_AVISION=255 scanimage 2>debug2 >image2
% scanimage -V
scanimage (sane-backends) 1.0.25; backend version 1.0.25

I investigated and tried 1.0.24 release after patching it to remove AV_FIRMWARE. It works great.

The only differences I see are:
