I am dealing with a scanner that seems to return some of its status outside the SCSI sense byte area. sanei_scsi reports this information via DBG but doesn't provide it to the sense handler. The data is in the SCSI header, which is physically adjacent to and preceding the sense bytes in sanei_scsi.c, so I can get to it with some C tricks. But, of course, those tricks could fail in a future SANE version. Is there a better recommended solution?
Here's the kind of debug output I'm seeing. [sanei_scsi] sanei_scsi_req_wait: read 64 bytes [sanei_scsi] sanei_scsi_req_wait: SCSI command complained: Success [sanei_scsi] sense buffer: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 [sanei_scsi] target status: 02 host status: 0000 driver status: 0018 [mybackend] sense=00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 The fourth line above shows target status and driver status. This information does not appear to be available to the sense handler. If sanei_scsi knows enough to call the sense handler in this case, and it does, it should provide all the relevant data. -- Dave Close Dreamworks SKG, Animation Technology +1 818 695 6962 Glendale California 91201-3007 dcl...@anim.dreamworks.com http://www.dreamworks.com/
