Hm. It works just fine reading 160kB using hpusbscsi on my HP Scanjet
5300 ... - Just vanilla source, nothing hacked.

Maybe I should use the sanei_scsi_open_extende and modify the
hpusbscsi module to let me pass such a huge amount of data ... (As far
as I can tell such a big transfer is currently only needed for the USB
devices. The SCSI ones can return the calibration data in smaller
junks ...)

No. I do not manipulate the BUFFERSIZE ...
