After upgrading to version 2.3.1-5 (normal sid updates), I no longer have the permissions for the /proc/bus/usb/003/nnn file changed from root,root for a Canon IXUS V digital still camera being plugged in.

Do you have any memory of latest working version ?  (was it a 2.3
serie ?)

Great, thanks for verifying this. This config option is by default
enabled, so you need to work hard to disable it :)

thanks,

It appears that the test kernels from kernel-archive.buildserver.net had CONFIG_USB_DEVICE_CLASS not defined.

I'm rebuilding 2.6.22-rc4 with CONFIG_USB_DEVICE_CLASS=y (will not have time to test it until about 24 hours from now).

It appears that the udev in Debian unstable still requires the backward compatibility provided by CONFIG_USB_DEVICE_CLASS=y

Arthur.
