Raspberry Pi DVD rom only partially showing in camcontrol

Hi,

I have a Raspberry Pi running FreeBSD 12, which I tried to open a USB DVD Rom on.
The output of camcontrol devlist -v results in this:

Code: 
scbus0 on umass-sim0 bus 0:
<SABRENT  0204>                    at scbus0 target 0 lun 0 (da0,pass0)
scbus1 on umass-sim1 bus 1:
<_NEC DVD+-RW ND-6650A 102C>       at scbus1 target 0 lun 0 (pass1)
scbus2 on umass-sim2 bus 2:
<Innostor Ext. HDD >               at scbus2 target 0 lun 0 (da1,pass2)

This looks like the DVD Rom is only partially there, but when I plug it into a computer running FreeBSD, it shows up and mounts just fine.

Code: 
scbus6 on umass-sim2 bus 2:
<_NEC DVD+-RW ND-6650A 102C>       at scbus6 target 0 lun 0 (pass7,cd1)

umass2: <Initio DVD+-RW ND-6650A, class 0/0, rev 2.00/1.06, addr 4> on usbus4
umass2:  8070i (ATAPI) over Bulk-Only; quirks = 0x4000
umass2:6:2: Attached to scbus6
cd1 at umass-sim2 bus 2 scbus6 target 0 lun 0
cd1: <_NEC DVD+-RW ND-6650A 102C> Removable CD-ROM SCSI device

But here is what it looks like on the dmesg bus on the Pi:

Code: 
ugen0.8: <Initio DVD+-RW ND-6650A> at usbus0
umass1 on uhub2
umass1: <Initio DVD+-RW ND-6650A, class 0/0, rev 2.00/1.06, addr 8> on usbus0

There is a powered USB hub between the drive and the Pi, so I don't thing power an issue.

Could there be a driver missing?
