Digital Camera modules

Toods · 03-21-2006, 04:10 AM

I want to connect my Fuji Digital camera as a USB device to retrieve images.

Could someone please tell me what kernel modules are needed for this as I currently compiled my kernel with them minimum number of modules and I fear more will be required?.

Thank you.

Have you tried connecting the camera without adding any more modules? I didn't have to do anything special with my camera, I just treated it like a mass storage device and did a:

Code:

mount -t vfat /dev/sda1 /mnt/camera

(where "camera" is a directory in /mnt obviously) and it worked just fine for me. Right now I'm using the bare kernel that came with the Slack 10.2 discs I burned so I haven't done anything fancy with kernel modules.

no, I haven't tried this yet, but I just suspect that when I recompiled the kernel, I trimmed-off too much.

These are the relevant sections of my .config file:

I have no idea what I'm doing when it comes to kernels and modules. I just got lucky and mine worked so I figured I'd see if I wasn't the only one.

Sorry I can't help ya anymore than that.

First try if it works with the modules that are compiled now.

Have you looked at the gphoto2 website http://www.gphoto.org/proj/libgphoto2/support.php if you need gphoto2 and libgphoto2 to access your camera?

I got a Fujifilm Finepix F810 that works nicely as a mass storage device. I have hotplug, udev and kernel 2.6.13 running. If you first check if your configuration is ok and if the camera works, I will post the parts of my kernel configuration here (the ones you posted).

Toods · 03-21-2006, 01:26 PM

Thanks for your replies.

I suppose what I could do then is to look at the '.config' file for the 'bare' kernel (2.4.32 I presume?) and probably figure out which modules I need by comparison with my kernel.

Try it first -- just my 2 cents. Imagine you search for kernel modules that you don't need ... Even if I post now my kernel config I could not tell if any differences to yours are significant regarding the usb mass storage thing. Maybe it works even if you changed the kernel configuration!?

Right, I've connected up the camera to the USB port.

It is seen when I do 'dmesg' and the usb-storage module is running as shown by 'lsmod', but when I try:

Code:

mount -t vfat /dev/sda1 /mnt/camera

I gat the following message:

Code:

mount: dev/sda1 is not a valid block device.

What am I missing?

Should I have declared /dev/sda in fstab for example?

Any help appreciated.

Thank you.

It works with my camera fine, but I don't know if you got another model and if this is handled different.
If I mount the camera as root with "mount -t vfat /dev/sda1 /mnt/camera" there is no error and I can browse on my cameras Xd card and view, copy etc. the files.

The modules that are loaded when I do this (I removed some which I'm sure are not involved with this but left some I'm not sure about, especially the nls codepage ones):

nls_cp437 5632 1
usb_storage 72512 1
ohci_hcd 18436 0
ehci_hcd 30344 0
uhci_hcd 30608 0
nls_iso8859_15 4480 8
nls_cp850 4736 7
evdev 7424 0

Did you search, if your camera is supposed to be recognized as mass storage device? Not all Fuji cameras are supposed to to so.

EDIT: I don't need an fstab entry, it should work if you mount it manually.

Toods · 03-22-2006, 04:51 AM

Thank you for your continuing help.

I think my problem is more to do with recognition of the 'sdx' SCSI drive. I have just looked through my kernel module config file and notice that 'CONFIG_BLK_DEV_SD is not set'. This is the 'SCSI disk support' module. I have a feeling this is the key, so I will recompile my kernel modules today and report back here.

Thanks again.

My general SCSI parts, after that there come some special SCSI devices:

#
# SCSI device support
#
CONFIG_SCSI=y
CONFIG_SCSI_PROC_FS=y

#
# SCSI support type (disk, tape, CD-ROM)
#
CONFIG_BLK_DEV_SD=y
# CONFIG_CHR_DEV_ST is not set
CONFIG_CHR_DEV_OSST=m
CONFIG_BLK_DEV_SR=y
CONFIG_BLK_DEV_SR_VENDOR=y
CONFIG_CHR_DEV_SG=m
CONFIG_CHR_DEV_SCH=m
