Digital camera Coolpix 2000 and kern 2.6.0


Hi all,

I don't know if this is the best place to post this because, probably, it won't be directly related to slackware but, since I'm using slack I'll post it here.

I've been trying to read the photos from my digital camera. It works under windows as it worked with my last Redhat linux.

I've recently migrated to slacware.Now I've installed kernel 2.6.0 and I can't read the compact flash from my camera. I think I've enabled all the modules needed in the kernel:

<*> DOS FAT fs support
<*> VFAT (Windows-95) fs support

SCSI support
<*> SCSI support
<*> SCSI disk support
<*> SCSI generic support

USB & USB Mass Storage
<*> Support for USB
<*> USB Mass Storage support[*] Microtech CompactFlash/SmartMedia support

Also, I can read perfectly my USB bar which should be almost the same thing: a usb device using mass storage protocol.

I must say I'm using supermount (that should be A MUST on every desktop box and should be merged in the kernel IMHO).

Using supermount doesn't work as it dosen't work manually mounting it. When I type:

mount -t auto (or vfat herer) /dev/sda1 /mnt/usb

it says "media not found".

If I type dmseg I can see the device have been correctly detected.

So, as you can see, I've tried many things before posting. I also looked other forums and did a little bit of googling with no luck.

If anyone knows the answer or have some ideas I'll like to hear'em.

Thanks in advance and sorry for my poor english.

SnOp

P.D.: I've checked anr re-checked cables and the camera itself. I'm pretty sure that the problem lays on the kernel because of a bad configuration or a bug.

Hi,
Your CoolPix 2000 is appearently supported by gphoto2, which has worked well for me. You can download a slack package that probably supports your camera from
http://www.linuxpackages.net/pkg_details.php?id=1957

Please note that your camera needs to be in PTP mode. On my CoolPix 4300, you go to the settings mode, select interface, USB, or something, and set it to PTP. Look it up in your manual (or try Google).
Also, several good GUI interfaces for gphoto2 are available. Kamera and gtkam are pretty good.

Good luck!

Hi again,

Thanks for the kind reply. Actually I've been trying gphoto2. Until now I haven't had no luck because it seems it can't detect any "valid ports" (I don't know what "port" means exactly for gphoto2). I've compiled gphoto myself and also tried the package pointed by tmorton.

Anyway, I'm gonna try again.

What I can't understand is that my usb bar works fine and my camera says "medium not found". I've checked and rechecked that the camera is using "Mass sotrage" and I've set it to "PTP" when trying gphoto.

Maybe it's because of supermount but I don't think so. I'll compile an unpatched 2.6.0 and try if it works.

C U

Hi!
I haven't tried gphoto2 under The 2.6 kernel, so it might be a problem there. Do you still have a 2.4 kernel you can try it gphoto2 with?

What does /var/log/messages give after trying gphoto2?

Hi again,

I haven't tried anything else yet because the camera isn't here. I'll put my "lsmod" output but I think it won't be helpfull 'cos I have almost everything compiled into kernel (at least all things related to USB). Anyway, here it is:

snop@server:~$ lsmod
Module Size Used by
nvidia 2072424 12
bttv 133024 0
video_buf 18944 1 bttv
btcx_risc 4868 1 bttv
tuner 15236 0
emu10k1_gp 3584 0
gameport 4736 1 emu10k1_gp
agpgart 27596 0

I must also say that I have a motherboard using an Intel chipset and I'm using UHCI, EHCI for the USB.

I want to try one more thing: unplug my wheel (logitech formula force gp) and try then. It may seem silly to try but the first time I booted slackware's installation cd it hanged at the point were USB devices were detected. Unplugging the wheel solved this.

I'll try to get the camera soon and do more trials.

Bye and thanks to everyone for your kind answers.
