My atapicam attempt is only a little bit further, the devices are there,
but they don't function:

I'm trying to use the CAM system for cd access under FreeBSD 5.1-BETA
as of Sat May 10.

I've set up the following devices in my kernel config:

device          scbus           # SCSI bus (required)
device          cd              # CD
device          pass            # Passthrough device (direct SCSI access)
device          atapicam        # emulate ATAPI devices as SCSI ditto via CAM
                                # needs CAM to be present (scbus & pass)

I see cd0 being set up nicely at kernel boot:

cd0 at ata1 bus 0 target 0 lun 0
cd0: <MATSHITA UJDA730 DVD/CDRW 1.04> Removable CD-ROM SCSI-0 device
cd0: 33.000MB/s transfers
cd0: Attempt to query device size failed: NOT READY, Medium not present - tray closed

The transport layer device /dev/xpt0 exists:
crw-------  1 root  operator  104,   0 May 10 19:50 /dev/xpt0

The CAM application passthrough devices /dev/pass* exist:
crw-------  1 root  operator   31,   0 May 10 19:50 /dev/pass0

So far so good, but every cam action I try fails :

# camcontrol devlist
camcontrol: error sending CAMIOCOMMAND ioctl: Inappropriate ioctl for device

# camcontrol rescan all
camcontrol: CAMIOCOMMAND ioctl failed: Inappropriate ioctl for device

# cdrecord -v dev=1,0,0 -dao *.wav
...
cdrecord: Inappropriate ioctl for device. Cannot open SCSI driver.

# cdrecord -scanbus
Cdrecord 2.0 (i386-unknown-freebsd5.1) Copyright (C) 1995-2002 Jörg Schilling
cdrecord: Inappropriate ioctl for device. CAMIOCOMMAND ioctl failed.  Cannot open SCSI driver.

Suggestions anyone ? (yes burncd works)
