[Wolves] ubuntu edgy camera problem

[baz]

When I plug my Canon A510 camera into my Ubuntu laptop I get this
error, 

'An error occurred in the io-library ('Could not claim the USB device'):
Could not claim interface 0 (Operation not permitted). Make sure no
other program or kernel module (such as sdc2xx, stv680, spca50x) is
using the device and you have read/write access to the device.'

Anyone help me sort this?
