no, the video player software. Say VLC or mplayer. Not to open a can of
worms but I would have called "firmware" the one "embedded in the
drive".

Anyway, the only reliable way that I know to play BDs with Linux is by
buying MakeMKV.
Last time I tried (and from archlinux's wiki things don't seem to have
changed much) the process of playing BD videos with free software
involves a lot of wine and chasing BD IDs and keys.
As for writing BDs, the drive should just appear as usb attached cdrom
writer using the scsi interface (i.e. using usb_storage and sr_mod),
i.e[1]:

   usb 2-2: new high-speed USB device number 5 using ehci_hcd
   usb 2-2: New USB device found, idVendor=0e8d, idProduct=1956
   usb 2-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
   usb 2-2: Product: MT1956
   usb 2-2: Manufacturer: MediaTek Inc
   usb 2-2: SerialNumber:
   scsi6 : usb-storage 2-2:1.0
   scsi 6:0:0:0: CD-ROM            TSSTcorp BDDVDW SE-506AB  TS00 PQ: 0 ANSI: 0
   sr1: scsi3-mmc drive: 0x/24x writer dvd-ram cd/rw xa/form2 cdda tray
   sr 6:0:0:0: Attached scsi CD-ROM sr1
   sr 6:0:0:0: Attached scsi generic sg2 type 5
   UDF-fs: Partition marked readonly; forcing readonly mount

The region-free bit of this discussion (which is 9 out of 11 messages so
far) is what I'm referring to as OT.
