I cannot connect my SONY DSC P12 digital camera via usb. Other usb devices like usb disk memory stick work without any problems. I am running RedHat7.3 with Kernel version 2.4.18-27.7.x. The following message appears in /var/log/messages:
Oct 29 00:12:47 klz1 kernel: hub.c: USB new device connect on bus3/1, assigned device number 2
Oct 29 00:12:47 klz1 kernel: usb.c: USB device 2 (vend/prod 0x54c/0x10) is not claimed by any active driver.
Oct 29 00:12:50 klz1 /etc/hotplug/usb.agent: ... no modules for USB product 54c/10/450

No virtual scsi device is assigned to the usb port. If I connect my USB disk, the message looks like this and I can mount the device:

What to do?
Thanks for help in advance.

Check out the site: http://www.gphoto.org/ I was able to get my Kodak DX3500 working with gPhoto. In Winblows, it connects like a drive, but not in Linux. Maybe your camera works the same way?

Sony DSC (Digital Still Camera)s use memory sticks in one of three modes that they call "normal", "PTP" and "pictbridge" which you select depending on your software. Linux detects it as a USB mass storage device and usually (Redhat 9 with 2.4.22 anyway) will give the option to mount it in the user mount tool as /mnt/camera.

You have to make sure you have the right modules loaded... but this worked out of the box for my DSC P32

gPhoto will support the Soney DSC-Px cameras in other modes.

My camera is not a sony, but what I do is just

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

So I have acess to the camera filesystem on /mnt/camera, like any other disk drive ...
