First post, glad to be part of the community.

I am posting in hopes of getting some assistance with my Casio Z50 camera. I am new to Linux, in fact, this is my first time playing around with it.

I'm running Slackware 10, and have all the recent Dropline packages. My problem is getting the /dev/sd* devices to display.

I am running the 2.6.11-rc2 kernel, and this is all the pertinent information.

Under my kernel configuration, I have ALL SCSI device support options enabled, just to eliminate the chance of having something I don't need. I do NOT use modules, everything is just compiled into the kernel, so there's no lsmod to output.

Support for Host-side USB (USB)
USB device filesystem (USB_DEVICEFS)
EHCI HCD (USB 2.0) support (USB_EHCI_HCD)
OHCI HCD support (USB_OHCI_HCD)
USB Mass Storage support (USB_STORAGE)

And HID support are what're enabled under the kernel.

What am I missing? What do I do to mount it? Why does nothing appear under /dev/sd*?

ANY help is greatly appreciated.

Well, first, try doing mount /dev/sda as root. (Just a note, for usb info, you can do lsusb).

Also, in the /var/log/messages, it says usb disconnect. Is it connected?

There's no /dev/s* devices to mount it with, this is the problem.

/proc/scsi/usb-storage exists when the device is on, when it's off, it's no longer there, so I know it's registering it, all the information is there, and then there's one item under usb-storage, namely:

lsusb does not list the device, but it also doesn't list the USB keyboard or mouse that both work.

What am I doing wrong?
As you can see, no SCSI devices to mount it with. :/

Hiya,

I'm using Slackware 10 with a Casio Ex100S (I think). My device was created automatically, so I guess that you've got something conflicting - software or driver.

When you boot, does the computer say something about starting hotplug devices ?
Is your rc.hotplug executable ?

iain@bob:~$ ls /etc/rc.d/rc.hotplug -l
-rwxr-xr-x 1 root root 1511 2004-06-21 05:34 /etc/rc.d/rc.hotplug*

Have you tried creating a device for the camera manually ?
(as root)
mknod -m 660 /dev/sda b 8 0
mknod -m 660 /dev/sda1 b 8 1

If you run 'lsmod', is usb_storage listed ?
iain@bob:~$ lsmod | grep usb
usb_storage 28544 0

Do you have other real SCSI devices ?

Iain.

Oh, I've also got a file called 000-homegrown.rules in /etc/udev/rules.d/

It uses a Udev rule to create a device called /dev/casio when the camera is connected. You could try the same :

iain@bob:~$ cat /etc/udev/rules.d/000-homegrown.rules
BUS="usb", SYSFS{manufacturer}="OLYMPUS", SYSFS{product}="C5050Z ", NAME="%k", SYMLINK="olympus"
BUS="usb", SYSFS{manufacturer}="CASIO COMPUTER", SYSFS{product}="CASIO QV DIGITAL", NAME="%k", SYMLINK="casio"

From what you've posted, and from the little I understand of Udev rules, this bottom line should work for you.

Oh. Just came to my mind to ask if you've configured your PC to use Udev ? (There will be lots of messages about it in /var/log/messages)
