The snapscan backend is not working properly with my Snapscan 1236s.<br>
'scanimage -T' fails on all tests, and the kernel reports this when I<br>
try to access the scanner:<br>
<p>
  kernel: (scsi0:0:2:0) Data overrun detected in Data-In phase, tag 0;<br>
  kernel:   Have seen Data Phase. Length=0, NumSGs=0.<br>

(Currently, the Snapscan scanner is not present).  Any ideas?<br>
