[CuBox] DVD drive not available

[togathMember]

Hi there,

I got a new DVD drive with USB2 interface for my CuBox

It’s recogised correctly:

usb 1-1: new high-speed USB device number 1 using orion-ehci
scsi3 : usb-storage 1-1:1.0
scsi 3:0:0:0: CD-ROM            TSSTcorp BDDVDW SE-506BB  TS00 PQ: 0 ANSI: 0

But the GUI doesn’t display any option to access the drive (neither audio CD nor video DVD)

I although tried this: http://www.geexbox.org/forum/topic/problem-with-opening-dvd/ without success.

I’m running the snapshot from 2013-10-05.

The drive works fine under Lubuntu 12.04

CONFIG_BLK_DEV_SR is not set on kernel ….. so your device is not attached to /dev/sr0
adding this now
but 3.1 release is already uploaded for cubox

Arrgh! Just noticed this as well. Another leftover from our kernel switch :-(.

[tomlohaveModerator]

Niko should rebuild the kernel on the afternoon, and re-upload all files.
It should be ready for this night.

Will test this then tomorrow with 3.1 Thank you

So, found some time for testing with v3.1

The device is recognised correctly as scsi-cdrom (dev/sr0):

# usb 1-1: new high-speed USB device number 2 using orion-ehci
scsi1 : usb-storage 1-1:1.0
scsi 1:0:0:0: CD-ROM            TSSTcorp BDDVDW SE-506BB  TS00 PQ: 0 ANSI: 0
sr0: scsi3-mmc drive: 0x/24x writer dvd-ram cd/rw xa/form2 cdda tray
cdrom: Uniform CD-ROM driver Revision: 3.20

Nevertheless that’s it. It’s not loading/mounting any disc.
In one out of ten auto-mounting attempts it produces at least an error:

# sr 4:0:0:0: [sr0]
Result: hostbyte=0x00 driverbyte=0x08

Buffer I/O error on device sr0, logical block 512

Same drive, same disc work fine on PC…

[tomlohaveModerator]

Ok, we are at least 2 .
I use the same external DVD drive on usb, On utilite, it works, on cubox, no
As we share the same packages with the same config, and I use the same device with the same disc, I think the problem comes with the kernel’s config. I will have a look at this and I hope I can find something.

[togathMember]

Hmmm … Is it good or bad that we are now 2?

If there is anything to support you in tracking it down, please let me know.

I figured out the following with that drive:
– If I connect it directly to CuBox it is recognised correctly.
– If I then insert a disc it starts reading it (spinning up the drive)
– Then it gets disconnected
– Then it gets connected again
– Starts reading in the disc
– …. endless connection/disconnetion loop

Therefore I assuem that it draws too much power from the usb when spinning up the drive. Which results in a disconnection (maybe intended to protect the CuBox HW maybe uninteded….)

I then used a y-cable with an external power-supply. With this I setup I get the result from my previous post.

[Warped RudiModerator]

Hmm, when trying some audio CDs last weekend, I noticed spindown/spinup and occasional hangs as well. I attributed this to the low quality drive I was using. May I should look again…

[tomlohaveModerator]

I use an external hub with its on power supply., so …

I bought today LG GP50 Slim black DVD/CD writer. As soon as possible I will write here my problems (I hope to not nothing write ^_^ ) about external DVD performances.
I have 3.1 of Geexbox and I think to use the drive without hub usb but connected directly to 2nd usb cubox usb port.

[tomlohaveModerator]

well, I spent some hours to test,
but so far I guess it’s a problem with the kernel itsel (but don’t why)
same hardware, same dvd disk work about of the box with c1, Utilite, … (and same configuration for kernel side and defconfig) so don’t know where to look now.

I add some infos. This is the output of lsusb comand :

I excepting to see something like ‘LG Gp 50 slim USB’….

I wrong something or kernel bug catch me?

[skelosParticipant]

My hardware was identified only after reboot. Geexbox support hot plug of USB DVD Writer?

[togathMember]

Sorry for my late reply. Was kept busy elsewhere.

I can confirm the ‘lusb’ command listing behaviour.

Bus 001 Device 002: ID 0e8d:1956 MediaTek Inc.
Bus 002 Device 002: ID 05af:0630 Jing-Mold Enterprise Co., Ltd
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

It would expect to read something like ‘Samsung BR/DVD’ instead of ‘MedaiTek’ (which is the manufacturer of the chip afaik)

Question: Was it working before the update to the new kernel? I never tested this before…
