Cannot mount usb-storage device (camera)

[Erhard Schultchen <eschultchen@gmx.de>]

Hi everybody,

I have been using my digital camera for quite some time now. However,
today it stopped working with my debian and won't come up again.
Hardware is OK, as Windows works *sigh*

So this is my setup: Debian/Sid, up-to-date, udev, hotplug and vanilla
kernels 2.6.1[12].

This is what I get in dmesg when I plug in the camera:

# dmesg

The camera is attached to an USB 1.1 controller (nforce2) but does not
work either on the USB 2.0. Hope someone can help with this - indeed
still worked a few days before.
