Camera problem

[Mike]

This is a repost:

I am no longer able to import photos from my digital camera (Nikon 
Coolpix 2100).
I am using Ubuntu version 8.04. I have used this version in the past to
import photos from my camera with no problem. Normally I store them in a
folder called Pictures and file an arange them with F-Spot.
The error I get is:
    Error connecting to camera
    Received error "Could not lock the device"
    while connecting to camera

Thanks - Mike
