Camera

Woofles · Posted: Tue Jun 03, 2003 2:21 am Post subject: Camera

I have a Nikon 5700 Digital Camera, and I am curious how I can make it work with Gentoo. It uses USB, any help is greatly appreciated.

P.S I'd prefer none of that B.S about buying a new Camera Thanks!

I've had success with gphoto2 (a command line interface) and its gui gtkam(gtk2 app).

It appears your camera is currently in the testing stages, which is has worked just fine for me
"Nikon Coolpix 5700 (PTP mode)" (TESTING)

First of all I would add "usb" to your USE variables in make.conf if its not already there. After that I would

emerge -p gtkam

and checkout the gphoto2 website.

I emerged GTkam with usd in my use flags, only seems to go up to Nikon Coolpix 990, I checked out the website and didn't find anything on the 5700 that I can download, only what you showed me. Anyinput?

What version of gphoto did you load? 2.1.1 I think is still only in ~x86. You can always get the CVS version from the gphoto site. They should be doing a new version soon and it will get into portage.

Alright, I figured out I had to get libgphoto2 emerged, it is now supported but it dosen't seem to deteect it now.... My computer has 4 usb ports two in the back and two in the front, it is the top one in the front any ideas on how to make it regonize it?

I have tried it as root also...

As always thanks for your help in advance!

Are the usb modules loaded?

The camera may simply look like a usb mass storage device to the computer so you may have to have the usb mass storage device module available.

This is what I have in /usr/src/linux under USB:

I've got the 5700 and I've just been using it through the USB storage interface. Mounting it by hand and transferring files. (I didn't realise it was now being supported albeit experimentally in gphoto2.)
To do this you need the USB storage element and the generic scsi emulation. (Which is under some esoteric place in the kernel I can't now remember fully - not in the SCSI section!)
Them, after plugging into the USB port, the device is available on /dev/sda1.
In the past, I had problems with the USB device being registerd by the relevant "bits", and had to "manually" force it through a ls of /dev/scsi/host0/bus0/target0/lun0/ (or whatever scsi chain turns up) to get a "part1" device, which then caused /dev/sda1 (/dev/sda to be absolutely correct i guess) to come into existence.
I must now have a look at gphoto support. (I thought it would come sooner or later as Nikons are pretty popular, and the 5700 seems the replacement for the 900 series.)

Stimpy, hmm.... I tried what you said, and didn't work... I currently use scsi emulation for my cdrw, couldn't get the camera trick to work

Anyway, now I have all the usb stuff as modules, and well still no luck with gphoto2, here is my lsmod :

Its the old "hmmm looks okay - but still not working" trick.
Basically I have the USB Devfs and SCSI emulation compiled into the kernel (I use it for cdrw as well.) I have all the other USB things I need as modules because I've been playing with switching my mouse from PS2 to USB.
For some reason I also have USB Storage as a module, which gets loaded automatically. (Go figure.)
The other modules I load in /etc/modules.autoload are: input, usbmouse and usb-uhci, which brings in hid and mousedev. Now I'm pretty sure these make no difference to the camera stuff.
Now looking at your lsmod output, it seems you don't have usb-storage. But I see earlier (I think) that you've compiled that in.
My only other advice is to look through the output from dmesg; when you boot, and when you turn on the camera. You may find something there. You also want to check you PCI devices that list your hubs and controllers.
Since making the earlier post I compiled up gphoto2, but have yet to get it to recognise the Nikon. I think it may have somethin to do with the PTP stuff and/or my particular controllers and kernel support. (That sounds good but I really haven o idea at the moment.)
I'll keep trying and keep you informed.

gphoto2 that is. (Apart from lots of obscure pango errors and other stuff...)
Things I found were:

The info is all in the gphoto setup guide and FAQ. You just have to know what to look for and try to understand whats going on.

note

I used the usbcam.console hotplug example BTW
Thats the nub of it. Check the info that you get from /proc/bus/usb/*
There's still some "bugs" that I need to iron out. eg the pango errors, and also how to use the save feature in gtkam (it seems to want to save the image and raw things in the same file.) but there's enough functionality there for it to be slightly more useful than the mass storage and mount approach.
In closing, key versions are: sys-apps/hotplug: 20020826-r2, media-gfx/gphoto2: 2.1.1-r1, and media-libs/libgphoto2: 2.1.1-r2. (I'm in the 2.4.20-r5 gentoo-sources kernel.)

Hmmm... I'm not sure what else to suggest besides getting the newest version just to be sure (Especially because support is only experimental...)
Also here's my menuconfig:
I should probably mention that even though I compiled USB mass storage support as a module, I don't load the module.

Woohooo I finally figured it out, I can mount it as /dev/sda1 now atleast, I'll work on the gtkam later, for now this will work. Thanks for your help folks

Sorry to be such a noob, but I am trying to manually mount my Olympus C-4000 camera manually. gphoto has difficulty recognizing it, so I am opting for brute force. Anyway, when I type:
mount /dev/sda1 /mnt/camera
the response I get is:
mount: you must specify the filesystem type

Ummm, what filesystem type do I specify?

Typically you want to use vfat as your filesystem type (See "man mount" for details on how to specify.) If that doesn't work, try umsdos.

Thanks! vfat worked like a charm. I'm curious though, why does the digital camera store images in the vfat format? I wouldn't think that would be the most efficient way, but then what do I know?

Stimpy, you rock. I've seen a zillion posts about the USB storage interface option, but you may well be the first to spell out where the dev ends up, i.e. /dev/sda#.

I can now access my Sony DSC-P31. (Unfortunately gphoto2 supports the DSC-P30 but not the -P31).

Thanks!

Would anyone be willing to collaborate on writing a Digital Cam Guide for Gentoo that details all of the various ways in which to get access to the camera?

I got my problem solved, it seems that sda1 was not created because i loaded the usb-storage module before loading sd_mod. So if anyone would have the same problem: load usb-storage last

I have an Olympus stylus 300. I have been reading through these posts and it seems that accessing the camera as a mass storage device seems to work for some people. How can I set up gentoo to mount /dev/sda1 to access the camera?

Thanks

I have installed the gtkam program as suggested in an earlier post, but I don't see my camera listed, I have an Olympus Stylus 300. Is there anyway I can install that specific camera, or is there another solution?
