I recompiled, installed and rebooted. But nothing changed. The messages
are as I already sent them. The only thing I can offer is the debug
output from the user level program "mscan":
--------------------------------------------------------------
scsi_open(/dev/scanner)
/* module gets loaded */
scsi_cmd 0x12 (write len=6, read len=96)
scsi_cmd 0x00 (write len=6, read len=0)

scsi_cmd 0x04 (write len=15, read len=0)
scsi_cmd 0x03 (write len=6, read len=4)

scsi_cmd 0x03 (write len=6, read len=4)
scsi_cmd 0x15 (write len=19, read len=0)
scsi_cmd 0x03 (write len=6, read len=4)
scsi_cmd 0x1b (write len=6, read len=0)
scsi_cmd 0x03 (write len=6, read len=4)

get_image_status: 154 bytes/line, 256 lines
scsi_cmd 0x08 (write len=6, read len=39424)
/* after about 5 seconds, the known error occurs, then: */
scsi_cmd: error (Device or resource busy):
sense=[00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00]
read_data: scsi command failed (-1)
scsi_cmd 0x1b (write len=6, read len=0)
scsi_cmd: error (Device or resource busy):
sense=[00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00]
stop_scan: scsi command failed (-1)
---------------------------------------------------------------
With the other driver (53c7,8xx), the output just ends after
"scsi_cmd 0x08 (write len=6, read len=39424)"
