Very Computer

After a bit of ferretting around, I found a few hints... and got this
far:

Being root;

modprobe usb-storage
modprobe uhci
mount -t usbdevfs none /proc/bus/usb

Now,
cat /proc/bus/usb/devices

gives this:

Now, usbview shows the camera. This is great... but how do I get
pictures off it?

ls -al /proc/bus/usb/

I think I can mount something from the usb bus as a filesystem, as if
it were a SCSI device, but I am unsure of the exact steps... Or is
there a way to configure gtKam (aside from the fact that the DSC-P71
is not in the list of supported cameras)?

First, I haven't plugged my DSC-S75 directly into my computer - I plug
in a cheap PQI memory stick reader, but I believe the result should be
nearly identical.

Try modprobe sg - this is "scsi generic support" for the kernel.  It
must either be compiled into the kernel or a module.

Then cat /proc/scsi/sg/device_strs - this should reveal:

  General         USB Disk Drive          1.00

& cat /proc/scsi/sg/host_strs should reveal:

  SCSI emulation for USB Mass Storage devices

& dmesg should reveal:

  SCSI device sdb: 7904 512-byte hdwr sectors (4 MB)

where "sdb" may be "sda" in your case; it's "b" on my machine since I
have scsi disk drives.

For my system, I executed as root "md /camera" & added this entry into
/etc/fstab:

  /dev/sdb1       /camera     vfat          user,noauto,rw,noexec

(which of course may need to be /dev/sda1 on your system).  Now, as
any user I can execute "mount /camera" & "ls -al /camera/dcim/100msdcf"
& all is good!

Good luck, Bob

I can use gtKam in "browse directory" mode to get the pictures, but it
is more useful to simply copy them and open them in Gimp.

But what I would *really* like to do, is drive the camera from the gtKam
interface; i.e. set the camera's parameters and take shots... I've tried
setting gtKam to use port usb: but I keep getting "Could not configure
camera"...
