If you remove the device from the SCSI bus (assuming your bus topology can support it), camcontrol rescan will detect that the device has gone, and all peripheral driver instances that were attached to the device will go away. The passthrough device attaches to any device that will respond to an inquiry. So even if you don't have a 'normal' device compiled into the system that will attach to a given device, you can always talk to it via the pass(4) device. Justin and I talked a bit yesterday about making the da driver a little more lenient about what errors it will allow on attach. I'm not sure I'm convinced we should. We'll have to discuss it a little more. The only problem you're having, really, is that you've got a weird device that doesn't attach under certain circumstances. I think the only oustanding issue with that MO drive is getting the da driver to attach to it when the media isn't spun up. The patches I sent out fixed (at least for Matthew Dodd) the case where there's no media in the drive, and it worked ok when there was spinning media in the drive.
