BTW: Joerg Wunsch, who advised me to state my problem in this list here, already
did have a quick look at the source of the driver. This is what he sent me:

case XPT_SCAN_BUS:          
{
#ifdef DC395x_trm_DEBUG1
printf(" XPT_SCAN_BUS \n");
#endif
pccb->ccb_h.status = CAM_REQ_INVALID;
xpt_done(pccb);
}
break;

...

case XPT_SCAN_LUN:         
{
#ifdef DC395x_trm_DEBUG1
printf(" XPT_SCAN_LUN \n");
#endif
pccb->ccb_h.status = CAM_REQ_INVALID;
xpt_done(pccb);
}
break;


From this fragment of code I really don't understand why there isn't at least
an error message.
And what is more: what happens when FreeBSD is scanning the devices on
boot-time? That procedure obviously is working fine...
