Patricio,
If you compiled Sane using the SG header files from the 2.4.0 kernel,
you problem may be related to a bug in sanei/sanei_scsi.c:
Near line 1900 in this file you'll find:
req->sgdata.sg3.hdr.timeout = 10000;
This should be changed to:
req->sgdata.sg3.hdr.timeout = 1000 * 60 * 10;
Without this patch, a SCSI command must be finished within 10 seconds;
the patch increases the time to 10 minutes, the same value as used by
Sane for older versions of the Linux kernel.
