USB camera devfs trouble

[je_fro]

Howdy,
On Gentoo, I'm having trouble mounting a Sony digital camera. I have the following kernel stuff that may be related to my problem:
CONFIG_HOTPLUG=y
CONFIG_PNP=y
CONFIG_BLK_DEV_SD=y
CONFIG_SD_EXTRA_DEVS=40
CONFIG_BLK_DEV_SR=y
CONFIG_BLK_DEV_SR_VENDOR=y
CONFIG_SR_EXTRA_DEVS=4
CONFIG_CHR_DEV_SG=y
CONFIG_SCSI_MULTI_LUN=y
CONFIG_SCSI_CONSTANTS=y
CONFIG_FAT_FS=y
CONFIG_MSDOS_FS=y
CONFIG_UMSDOS_FS=y
CONFIG_VFAT_FS=y
CONFIG_SUPERMOUNT=y
CONFIG_DEVFS_FS=y
CONFIG_DEVFS_MOUNT=y
CONFIG_USB=y
# CONFIG_USB_DEBUG is not set
CONFIG_USB_DEVICEFS=y
CONFIG_USB_EHCI_HCD=y
CONFIG_USB_UHCI_ALT=y
CONFIG_USB_OHCI=y
CONFIG_USB_STORAGE=y
CONFIG_USB_STORAGE_DEBUG=y

Now, when I first plugged in the camera, usbview showed a Sony device attached. After stopping and starting the camera (to try to find the device) it only shows "Unknown Device", and it keeps on showing even after the camera is off. (I'll reboot later to see if it's still there. It may always be there.)
For the record, I am using the nforce2 chipset on an Abit-NF-7S MoBo, so that may also have something to do with it.
Dmesg gives this:

i'd report it to bugs.gentoo.org

especially if it works after a reboot but fails again after a disconnect / reconnect.

By trying gtkam, I found out that "PTP mode" is supported. I can almost mount the camera. It has become mostly a permissions issue. Root can view a few photos with gtkam, but I can't find the device to mount it. I get this in log:

Jul 10 01:01:54 [su(pam_unix)] session opened for user root by je_fro(uid=1000)

Jul 10 01:02:42 [gconfd (jeff-7180)] starting (version 1.0.8), pid 7180 user 'je_fro'

Any ideas how I can find the device other than trial and error?

I have no new sr or sg devices...can't find it anywhere.

Hmm... this message means that none of the USB drivers that your kernel has loaded are claiming that specific device type (or that specific device, I'm not 100% sure how it works). If that helps you at all...

It could be completely normal, actually. My LFS init scripts actually cause this error when they load USB support up -- when the USB bridge module is loaded (uhci.o), my USB mouse is connected, and my kernel logs a "usb.c: connect" message for the mouse, then a "device X is not claimed by any active driver" message a bit later, because I don't have any modules loaded that are saying "yeah, I'll take that mouse". When the init scripts later load the hid.o and mousedev.o modules, the kernel says "OK, now there's a USB driver loaded that will take that mouse, so I'll set up what's needed". It never logs any success message then, though.

This doesn't sound like exactly what's happening for you, since it doesn't end up working, but maybe it provides some insight? Maybe you just need to load an extra module? usb-storage is a good candidate, usually...
