External BD-Rom drive over PATA to USB Adapter only works with DVDs

Support
1

Hi,

I am trying to use an external drive to play Blu-Ray Movies, but only DVDs seem to play properly.

I am using an external Blu-Ray Shell with a slimline drive mounted in it.
LSUSB displays the device as:
Initio Corporation INIC-1511L PATA Bridge

The drive is a:
Sony Optiarc BC-5500a BD-Rom Drive

When connecting the device the drive name is displayed properly, but as far as I understand the dmesg output it only loads as a dvd-drive:

[  134.957872] usb 1-2.3: new high-speed USB device number 8 using xhci_hcd

When putting a Blu-Ray into the drive the following output appears:

I checked that libbluray is installed, and added libaacs.

running bd_info /dev/sr0 results in

Using libbluray version 1.3.4
disc.c:333: failed opening UDF image /dev/sr0
disc.c:437: error opening file BDMV/index.bdmv
disc.c:437: error opening file BDMV/BACKUP/index.bdmv
bd_open('/dev/sr0', '(null)') failed.

Is this an issue with the Drive or the Bridge/external case?
I have not tried a windows system yet, since I do not have one easily available to verify the operation.

It is simply DRM → Digital Right Management. Take a look at Blu-ray - ArchWiki

3

I did the preparations under 2.1 earlier already.

When retrying a BD-ROM I do not get the output on dmesg any more, but I still seem unable to play anything, and bd_info (section 2.2) still gives the same error

4

Probably it is BD+ protected? See section 2.3.3

Also see: section 2.5.4

sudo modprobe sg
5

sg didn’t fix it.

The libbdplus installation seems quite complicated.
Is there an easy way to see which discs are bd±protected? I have various discs available I could use for testing

6

Check it with aacs_info on the terminal. Then it is AACS protected and not BD+.

7

The aacs_info seems like it can’t properly access the disk

aacs_info /dev/sr0

Looks like the drive is not capable to read encrypted Blu-rays… Buy a new one? Probably try that drive on WIndows or Mac…

I just checked the drive on windows, and after installing libaacs it ran the same blu ray without issues.
I also tried the other path for the keydb file on manjaro, but that didn’t change anything, I was suspecting permission issues.

It looks more and more like a driver problem to me. On windows even without the keys the disk spins up and runs much longer, while on linux there are only sounds for a short moment before it seems to go into a standby mode.

10

You run that as root and not as user, correct? Because a # on the terminal means “root permissions” and $ means “user permissions”. So run it with sudo to get root permissions. I thought you know that.

sudo aacs_info /dev/sr0

or

sudo bd_info /dev/sr0

Sorry, I thought you used the root account, since dmesg needs that also.

If it really a suspend problem, then see TLP to disable AUTOSUSPEND for USB devices…

11

Everything was run as root. I just wasn’t sure what the right permissions of the config file were.

I changed autosuspend, but there was unfortunately no difference

12

Yeah, it sucks. DRM is and was always a pain on Linux, because it is mostly reverse-engineered. In case of DVD and BD.

I would advise you to look into Makemkv and VLC. Makemkv is shareware and can emulate libaacs and libbdplus.

Whish you good luck with that, since I don’t own a BD-Player.
