Linux Kernel 2.4.31 and HP nc4010 ...

Hi,

I have big troubles with Linux Kernel 2.4.31 running on my HP nc4010.

Symptoms :

The external Combo DVD/CD-RW (DVD & CD Burner) was not correctly detected at all :

The /proc/sys/dev/cdrom/info :

CD-ROM information, Id: cdrom.c 3.12 2000/10/18

drive name: sr0
drive speed: 1
drive # of slots: 1
Can close tray: 1
Can open tray: 1
Can lock tray: 1
Can change speed: 0
Can select disk: 0
Can read multisession: 1
Can read MCN: 1
Reports media changed: 1
Can play audio: 1
Can write CD-R: 0
Can write CD-RW: 0
Can read DVD: 0
Can write DVD-R: 0
Can write DVD-RAM: 0

The right capabilities must look like :

CD-ROM information, Id: cdrom.c 3.20 2003/12/17

drive name: sr0
drive speed: 24
drive # of slots: 1
Can close tray: 1

Can write DVD-R: 0
Can write DVD-RAM: 0
Can read MRW: 1

Any idea why the device doesn't work under 2.4.31 (i'm really doubt this conventionnal device can't work under 2.4.xx series ...)

You might with to try it under the 2.6 Kernel.

Your kernel is reasonably up to date for 2.4 though. Perhaps its a bios settings issue. Maybe take a look there.

Hi Steven,

Obviously i have tested the device under 2.6.xx series (the rights capabilities in my 1st post are for the device running under 2.6.12.4 latest).

But for a personnal choice i prefer to use 2.4.xx series ...

By the way, i do not understand why a standart device like the USB Combo DVD/CD-RW Burner was not supported under 2.4.xx kernels series.

I'm pretty sure the problem come from the USB to IDE bridge chipset used in the HP Multibay, because if i use the Combo connected by IDE bus directly, it was correctly detected (rights capabilities) and work properly under 2.4.31 ...

I have also found 2 references for HP Multibay :

- DC373B#B13 (i actually own this one)

&

- DC373B#ABA (another one)

Maybe the USB to IDE bridge chipset used in the ABA version was different than the one used in the B13 version ... ???

Googling on the ABA version, i see it was also used has external Multibay for a t5125 Thin Client running Linux Kernel 2.4.xx series.

If someone at HP side can give feedback about the DC373B#ABA under Linux Kernel 2.4.xx, it would be great ...
